Outcome

Improve end-to-end REA investigation efficiency while preserving the working CLI/MCP workflows of existing users. Implement three increments in this order:

1. Measure the actual costs and improve known nested result types and caller-selected Evidence views.
2. Evaluate explicit, task-verified Ghidra analysis presets using the existing analyzer controls.
3. Pilot a small, statically composed domain-module descriptor for WASM or EVM, without introducing a general plugin ecosystem.

This is a concrete implementation and real-artifact verification follow-up to #740 and #1065. Those issues remain the owners of their broader architecture and performance roadmaps. Evidence lifetime design remains associated with #721; real demonstration coverage is related to #778.

The study starts from frozen main 42b0ed126df7d5b908ac369715378d5e519051b7 (2026-10-12 UTC). Each experiment records its own immutable runtime/corpus/provider pins; later integrations do not relabel the original measurements. Version publication and deployment remain outside this work.

Completion review — 2026-10-14

The original three increments are complete within their recorded scope: measured costs and typed opt-in result delivery; task-scoped Ghidra profile evaluation/lifecycle verification with unchanged defaults; and static WASM/EVM descriptor pilots with exact contracts and retained cleanup ownership. All 34 listed acceptance items have recorded evidence, and all 15 related implementation/experiment PRs are merged and present in main f3534749e564421036ac445f536fc766b038208f.

Measured decisions remain task-specific. Flutter/LocalSend's two actual model pairs reduce total input by 42.38–48.75% and task time by 23.95–30.30%. QGIS SQLite's existing column selection reduces total input by 36.44–57.63%, with mixed task time and no new API. Compact HTTP PCAP summary/page increases total input by 50.54–50.92%, so complete defaults remain the appropriate choice for that question. Descriptor wiring itself is not a token/speed improvement, and reduced Ghidra analysis lost callee facts, so no general fast preset is recommended. CPU/memory safeguards and phase measurements do not establish universal resource savings or verified unavailable terminal counters.

Additional protocols/artifacts/hosts, general plugin SDK/ABI admission, and persistent cross-session engine caches are optional follow-up work rather than unfinished requirements of the original scope. Existing-user and old-Evidence compatibility are supported by the pinned invocations and migration checks; every historical client/platform is not claimed verified. This review reconciles implementation and preserved evidence; it does not rerun the full real-model/provider matrix. The original scope is closed as completed; further measured opportunities are owned by the separate issues listed below.

Follow-up handoff — 2026-10-14

Closed as completed: all 34 recorded acceptance items for #2016 have scoped evidence, and its 15 related implementation/experiment PRs are merged. The original design, immutable measurement pins, positive/negative findings and compatibility qualifications remain here as the completed record. Creating the independent follow-ups does not reopen the original scope or claim new performance results.

Follow-up	Issue	Completion boundary
Larger/non-HTTP captures	#3130	Existing discovery/field/filter controls, repeated dissection and real token/time comparisons
Recorded signals	#3131	Decoder/channel/annotation selection and repeated display-page costs
SAZ archives	#3132	Existing summary/retained transaction views on genuine public recordings
Qlog recordings	#3133	Supported trace/event/summary workflows with truthful declared-event semantics
Large retained investigations	#3134	Existing paging, producer reuse and authentic old-Evidence continuation
Remaining real-artifact/provider gaps	#3135	Bounded planning: rank at most three precise next pilots, not an all-domain benchmark
Ghidra engine reuse — research gate	#3136	Establish demand and measured benefit beyond existing snapshots/#1048 before any persistent cache
External modules — research gate	#3137	Establish concrete demand and compatibility criteria before an SDK/loader/ecosystem

All eight follow-ups carry exactly the same labels as #2016 (enhancement, P1: high, area: domain, roadmap, performance, design) and are assigned to N0zoM1z0. Each contains its own analyst question, bounded work, evidence/acceptance contract and compatibility/resource constraints. Broader roadmaps remain with #740/#1065; existing feature owners are linked rather than duplicated. Start with #3130 for the next measured capture round; #3136/#3137 are demand-gated research, not an instruction to implement caches or a plugin ecosystem.

Relevant experimental decisions belong in their new owning issue. PR-specific CI/review/rebase progress belongs in the corresponding PR; unrelated product defects remain in the local team handoff. Existing controls may be sufficient, and a well-supported no-change or unavailable conclusion completes the relevant research task.

Optimization priorities and progressive migration

The two primary objectives are agent token consumption and end-to-end task time. Memory and CPU consumption are also optimization objectives and remain bounded throughout experimentation. Correctness, meaningful Evidence/coverage, caller choices, and compatibility for existing users are acceptance conditions: a smaller or faster incomplete answer is not an improvement for the same question.

Objective	What to measure and optimize	Interpretation boundary
Agent tokens — primary	Necessary model-visible facts and useful provenance; discovery context; total/cached/uncached input and output; calls, retries, errors, and follow-up turns for the same analyst question	Avoid overwhelming the agent with unrelated bulk data. Compact JSON byte reduction is a delivery result, not an exact token reduction. A smaller response must still let the agent answer the question.
Task time — primary	Time to a factually acceptable answer, including provider startup/analysis, transport, client processing, model turns, and corrections; separate cold/warm conditions and observable stages	Fewer bytes or one favorable model trial does not establish a general speedup. Repeat comparable trials before extending a claim.
Memory	Aggregate process-tree peak/limit events; retained Evidence; object/serialization expansion; worker/engine usage; verified cleanup	Preserve host safeguards and no-OOM operation; moving allocation between processes is not proof of lower aggregate memory.
CPU	Aggregate CPU time needed to complete the same question, plus observed stage timings where available	The one-CPU quota is an experiment control, not a demonstrated CPU saving. A shorter wall time is not automatically lower CPU work.

Prefer explicit, focused result delivery and reuse of retained Evidence where these preserve the requested facts. Keep existing complete requests available and unchanged. Do not silently reduce engine analysis, truncate Evidence, change source selection, or change a caller's provider to improve a metric.

Verification and migration are progressive. Extend the domain matrix one bounded step at a time, with real shipped artifacts for the changed domain and relevant shared-contract regression checks. Completing every advertised domain in one pass is not required. Native Windows PE and original UPX-compressed DOS MZ have been statically verified through Linux Ghidra in #2216. Native Windows runtime behavior, unpacked DOS editor logic and DOS COM remain unverified; managed PE/CLI does not substitute for native PE. Firmware region inspection, selected JavaScript AST analysis, and browser capture each retain their stated narrower coverage. Preserve unavailable and incomplete outcomes rather than treating them as global successes.

Compatibility directions are explicit:

• Existing clients / new REA: existing names, accepted arguments, complete defaults, provider choices and session semantics must continue to work. The current pilot is additive and opt-in; existing users need no new pack or request rewrite to retain shipped capabilities.
• Existing Evidence / new REA: preserve authenticated original records and IDs during import, inline use, new views and export. Actual baseline SQLite/Obsidian migration is recorded in the linked checkpoint.
• New capabilities / older REA: clients must discover the actual advertised schema and use supported existing equivalents where available. Older servers do not automatically understand the newly added selectors. A universal automatic fallback is not implemented or claimed by this study.

The current evidence is pinned to the recorded baseline, clients and real workflows; it is not an unconditional guarantee for every historical release, OS or third-party integration. The earlier 259e99dd9 runtime grows the complete catalog about 2.6% in compact JSON; the later main-integrated runtime records about 1.4% growth versus the original baseline, including intervening main changes. Keep this discovery cost visible alongside selected-delivery savings. Existing complete requests do not automatically receive the new token-saving delivery path. Newly found REA bugs remain documented locally for later team repair, as requested.

Evidence motivating the sequence

The previous optional Code Mode experiment is pinned at e65a13f54, using the earlier frozen production baseline fb94d9dde0ccda83ae520ac6fb22b1d283562cf3.

• Decision and migration boundaries
• Measured cohort and fingerprints
• Results, failed attempts, and verification limits
• Real artifact provenance and digests

Sixteen serial real Codex CLI trials, configured with gpt-5.6-terra high, covered Android, managed PE/CLI, Electron inventory, firmware, and Ghidra native analysis. Twelve passed the requested fact/reference assertions. Two bridge managed answers omitted a classification field; two direct managed JSONL transcripts truncated a producer envelope and prevented complete-envelope reference verification. These are different failure classes, and the stronger complete-classification assertion exceeded the question's general wording.

The bridge did not establish a stable overall speedup:

• Android bridge repetitions took 48.231 and 134.555 seconds, compared with 67.329 and 71.624 seconds directly. The model did not consistently select one composed execution.
• Guided Electron inventory reduced total input from 263,484 to 101,994 tokens, but uncached input only from 41,532 to 40,554; bridge wall time was 85.909 versus 67.540 seconds. Context compression is not equivalent to cost or latency reduction.
• Ghidra took 334.642 versus 327.150 seconds with unchanged analysis settings. Provider CPU remained the dominant measured work.
• SQLite WASM exposed a frozen WABT row-parser failure. Obsidian full AST analysis timed out with a retained partial reference. Neither is a successful Code Mode result; successful inventory answers do not replace AST analysis.

The existing bridge receives complete upstream results before projecting them. It can reduce model-visible data while retaining upstream analysis, serialization, transport, parsing, Evidence, and guest-transfer costs. REA already has typed domain ports, canonical named contracts, provider factories, owned-process primitives, snapshot replay, and retained Evidence views; reuse these rather than rebuilding them.

Compatibility contract

Compatibility is an acceptance condition for each increment, not a final documentation exercise.

• Keep the normal distribution usable with its existing capabilities. Existing users must not have to discover and install new packs merely to regain previously shipped tools.
• Preserve existing CLI command names, MCP tool names, argument meanings, caller-selected targets/providers/paths, defaults, result fields, structured/text delivery, and tagged failure semantics.
• Do not silently narrow the set of supported old inputs while improving producer output typing.
• Preserve the default complete-result path. New focused views, module selection, and analysis presets must be explicitly selected; no silent truncation or automatic switch to reduced analysis.
• Preserve the default complete and stable tool catalog. Any experimental pack-selection profile is explicit and fixed for that connection; opening a target must not remove tools.
• Configuration changes are additive and idempotent, with backups when files are written. Retain existing environment/configuration names and meanings. Do not install or upgrade unrelated host software.
• Preserve existing Evidence identity, raw/normalized distinctions, uncertainty, coverage, authority, session retention, and export/import behavior. In particular, do not silently change the default close_binary record lifetime.
• A derived view receives its own identity and links to its parent Evidence. A caller projection must not masquerade as the original canonical record under the parent's ID.
• New clients using new capabilities against older servers must discover actual support and use supported existing operations where an equivalent workflow exists; report unavailable capabilities honestly. Never change a caller's provider choice to create an apparent success.
• Use pinned pre-change invocations, configuration fixtures, and actual CLI/MCP clients as compatibility evidence. Pure composition changes should preserve catalog schemas/digests and public behavior; intentional additive schema/view changes require their own consumer checks.

Target architecture and ownership

The diagram below translates and tightens the architecture proposal. Solid arrows describe interface dependencies or provider execution; dashed arrows describe explicit production composition. Domain and application contracts do not import engine protocols. This is a target boundary map, not a proposal to move every file or ship three new package systems at once.

The extension roles remain separate:

Role	Responsibility	Ownership boundary
Domain module	Domain schemas, query/view semantics, precise capabilities, and existing registration metadata	Reuses pure models and typed ports; does not own a universal engine protocol
Engine adapter	Version/support inspection, protocol parsing, analysis implementation, process and target session	Implements applicable ports; owns and cleans up its acquired resources
Workflow	Compose compatible domain facts to answer a recurring analyst question	Uses typed operations and source Evidence; does not construct duplicate engine sessions
Composition host	Bind exact contracts to implementations and register acquired resource ownership	Explicit static composition first; preserves healthy peers and failed-cleanup ownership

Existing entry points retain their public behavior. The first descriptor pilot is an internal wiring change. A native and a firmware workflow can share an adapter implementation while still requiring separate Program instances for distinct targets. Reuse of a live instance requires matching target/profile/revision and a single clear owner.

Engine sessions and investigation Evidence have different responsibilities, but the first increments preserve the existing record lifetime. They do not silently retain records after close_binary; portable export/import is the initial cross-session continuation.

Increment 1: cost measurement and precise result delivery

Establish a comparable baseline

Record artifact and provider digests, exact revision, operation arguments, analysis settings, CPU/memory limits, client/model configuration, and cold/warm state. Separate:

• Engine launch, import, auto-analysis, readiness, and first/warm query where those stages are observable.
• Queue wait and provider operation time.
• Result assembly, validation, retained Evidence/cache work, serialization, transport bytes, and client parsing/validation where measurable.
• Tool discovery, model turns, repeated operations, failures/retries, API token usage, complete task time, and useful answer quality.

Add instrumentation at the boundary that owns each measurement. Diagnostic timing must not change canonical Evidence identity or retain an unbounded history. Report unavailable stage measurements explicitly rather than inventing a decomposition from total wall time.

Improve known nested payloads and selected views

Start with inspect_artifact's nested inventory Evidence and the existing inspect_analysis_view machinery. Where an operation guarantees a known payload, advertise and validate its concrete nested structure instead of generic JSON. Reuse canonical schemas to derive authoring types and examples.

For repeated questions such as manifest, entry-kind counts, and selected root occurrence records, offer the smallest justified caller-selected view, with the selection scope, original identities, coverage, unknowns, limitations, and contributing Evidence links. Retain the complete source record under its existing lifecycle. Repeated views must not re-run the producer.

Measure the changed SDK-converted catalog as well as runtime results: a more precise schema can increase discovery size. Validate the declared JSON Schema dialect and actual client calls. View projection after analysis and producer-side query pushdown are separate experiments; do not claim saved engine work from a smaller response alone.

Acceptance:

• A pinned, reproducible baseline distinguishes measured costs and unknown stages.
• Known nested output is validated and discoverable through the actual SDK/client boundary.
• Existing full output/defaults and old inputs remain usable.
• Focused results preserve meaningful source, selection, uncertainty, and coverage.
• Retained follow-up does not re-run the producer and survives relevant partial failures.
• Real large-artifact runs show the measured benefits and any regressions, including parsing/serialization and peak memory.

Increment 2: explicit, task-verified analysis presets

Use the existing REA_GHIDRA_DISABLED_ANALYZERS support and committed analysis profile. First measure default behavior; then evaluate one narrowly scoped alternative against exactly defined analyst questions.

• Keep the default profile unchanged.
• Specify engine version, applicable target formats/languages, selected settings, task scope, evidence available, and explicit unknowns.
• Measure cold startup/import/analysis and warm query separately; use matching CPU/JVM limits.
• Verify the task's necessary facts, not just shorter wall time. Missing xrefs under reduced analysis do not establish their absence.
• Keep effective settings in profile/cache identity. Old cached results must not be replayed under a different preset.
• If later work introduces incremental analysis, it needs an explicit readiness/analysis revision and coverage commitment. That lifecycle change is not required for this first preset experiment.

Acceptance:

• Existing default invocations produce compatible behavior.
• The selected alternative is verified on real shipped binaries with pinned questions and producer evidence.
• Profile differences and limitations are visible; cancellation, failure, cleanup, and snapshot compatibility are covered. Verified in #2349 with actual Linux Ghidra 12.1.4 default/disabled profiles, GNU true and jq snapshot workflows, startup cancellation, invalid-analyzer failure, and permission-induced cleanup retry; this does not imply other OS/provider coverage.
• Any performance recommendation is restricted to the tested task/format/provider scope.

Increment 3: one small domain-module descriptor pilot

Choose WASM or EVM based on the refreshed source and provider results. Keep one local distribution and explicit static composition. The descriptor should bind existing exact contracts, typed service/provider factories, adapter registration, availability/effects, and owned cleanup. Preserve compiler checks inside each module and validate unknown values at actual dynamic boundaries.

Maintain these ownership rules:

• Pure domain data/semantics and typed application ports remain independent of specific provider protocols and CLI/MCP implementations.
• Composition constructs implementations and injects them. A module descriptor must not become a provider-specific dependency in core domain code.
• Domain, engine, and workflow extensions remain distinct. Complementary Android bytecode/resource/runtime capabilities must not be forced into one interchangeable universal provider interface.
• Sharing an engine adapter is not sharing one global Program/session. Reuse requires the correct target, profile, revision, and owner; different targets retain separate mutable analysis state.
• Resource registration happens when the module acquires resources. Failed cleanup retains ownership and permits meaningful recovery; unloading must not discard an owned resource merely because close failed.
• Optional module failure must preserve healthy peers and disclose the failure.

Acceptance:

• One domain is wired through its descriptor with fewer independently maintained core registration/cleanup points.
• Default catalog, old CLI/MCP inputs/results, provider choices, and lifecycle behavior remain compatible.
• Duplicate names and incompatible contracts fail clearly before use. Scoped to the static pilot: #2427 verifies exact operation/CLI/factory/input/output assignability in the complete compiler gate and actual SDK duplicate registration before any provider call. Dynamic third-party ABI/version admission is not introduced; validating unknown provider replies after execution remains a distinct boundary.
• Actual CLI/MCP workflows cover unavailable providers, malformed inputs, cancellation, capacity, partial failures, and cleanup retry. Linux x64 real EVMole/prlimit verification from #2261 and #2404, including actual worker replies, late SDK cancellation, permission-induced retained cleanup recovery and a healthy real WABT peer; mid-WASM interruption and other hosts are not claimed.
• Packaging and generated projections remain derived from owning source.
• The changed architecture is followed by cross-domain real-artifact regression, not only recording-port tests.

Real-artifact and real-model verification

Reuse the previously digest-verified public corpus where suitable, and add public shipped artifacts for uncovered available domains. Keep binaries, provider projects, raw target output, temporary credentials, and local profiles outside Git. Record acquisition URL/version/digest and preserve exact target bytes.

Lane	Initial real artifact / workflow	Required evidence
Native	jq 1.8.2; add a larger public binary for preset evaluation	Target identity, known selected procedures/relationships, default versus explicit profile, readiness and cleanup
Managed PE/CLI	ShareX 19.0.2 assembly	Assembly/module identity, selected members/native boundaries, complete classification and explicit coverage
Android	NewPipe 0.29.1 APK	Package identity, selected classes/methods, descriptor/null semantics, real JADX results and cleanup
Electron/package inventory	Obsidian 1.14.4 ASAR	Complete source inventory retained; manifest/counts/selected paths, contradictions, AST unknowns, view parity
JavaScript/AST	Public shipped JavaScript artifact with a bounded, meaningful static question	Actual producer facts, partial/timeout outcome when applicable, retained continuation; inventory is not an AST substitute
Firmware	OpenWrt 25.12.5 Archer C7 v5 image	Real Binwalk/Unblob observations where available, offsets/sizes, engine identity, signature-scan coverage
WASM	SQLite Wasm 3.53.4-build1	Real pinned WABT output, format-aware parsing, complete/failed coverage and target digest
EVM	Public deployed bytecode with recorded source provenance	Original carrier and decoded-byte identities, inferred selector/interface facts and unknown authenticity/completeness
Browser/runtime	A controlled owned browser capture of a real public application when the host supports it	Actual capture/source attribution and owned lifecycle, with explicit runtime authority

Extend this matrix to other advertised domains affected by the composition change. Distinguish an unavailable OS/engine/input lane from a passed real-provider test. Linux results do not prove Windows/macOS, Hopper, IDA GUI, ADB-device, or other unavailable provider behavior. Real application and real-provider success must never be inferred from simulated ports.

Run comparable fixed replays first to isolate implementation cost, then use real Codex CLI with temporary isolated configuration pointing to the modified REA MCP. Keep the requested model/configuration explicit; initially reuse gpt-5.6-terra high for comparability. Grade requested facts, explicit unknowns, cleanup, and source references against actual producer evidence. Verify per-claim support where feasible, beyond merely seeing a valid ID in a transcript. Save failures, retries, transcript truncation, and timeouts in the results.

Separate cold/warm sessions and cache states, interleave pair order, and repeat representative pairs. Record total/cached/uncached input and output separately without treating token totals as currency cost. Claims remain descriptive until the sample supports stronger conclusions.

Host resource controls

• Heavy builds/tests/provider/model trials run serially in owned resource scopes.
• Initial aggregate trial limits: one CPU, 4 GiB hard memory ceiling, 3 GiB early-stop threshold, no swap growth, and bounded tasks; refuse starts when host available memory is low.
• JVM/Node/worker limits fit within the aggregate budget. Account for object copies, serialization expansion, retained Evidence/cache, and temporary disk before increasing concurrency.
• Record sampled family memory/tasks, CPU usage, resource-limit events, timeout/abort reasons, and owned cleanup. A limit event invalidates a purported successful performance run.
• Delete disposable model profiles and copied authentication material on success, failure, cancellation, and timeout. Do not capture the ambient environment.
• Do not kill processes using a PID alone or touch user-owned GUI databases. Preserve owned resources whose cleanup is unverified.

Deferred decisions

General third-party plugin SDK/distribution, automatic plugin discovery/hot reload, cross-session Ghidra database persistence, and broad shared-query concurrency are deferred until actual demand or measured repeated work justifies their compatibility and lifecycle costs. Code Mode remains optional; this issue does not switch existing users to the external bridge.

Completion evidence

• Commit the implementation, relevant compatibility/boundary tests, source-authored documentation, and curated measurements.
• Run appropriate source, focused artifact, typecheck/lint, schema, generated-doc, packaging, and real-provider checks for the touched boundaries.
• Repeat the available real-domain matrix against the modified runtime after the descriptor integration.
• Publish a final issue update linking commits and describing what changed, measured outcomes, compatibility evidence, failed attempts, and unverified lanes.
• Push progress to the implementation branch and create the explicitly requested review PR (#2122); the maintainer subsequently authorized a verified merge and continued work; version publication and deployment remain unauthorized.

Experiment record ownership (2026-10-12)

Detailed generated result JSON is archived byte-for-byte outside the checkout and excluded from the final PR tree. Source-owned corpus inputs, reproduction scripts, measured findings, frozen revision/digest references, compatibility qualifications remain in the experiment notes. Historical checkpoint commits remain intact.

Latest-main continuation: newer capability efficiency audit (2026-10-13)

The refreshed main pin is f254f5ac2b804b353a711264bb178f43fdf07867, unchanged since the preceding Android merge. This continuation audits features added during the earlier implementation cycle that were not all included in its final performance matrix; it does not claim new commits after that merge. Work is isolated on perf/latest-main-efficiency-20261013 in a fresh worktree. Original completed acceptance evidence remains intact.

Capability	Existing delivery/ownership controls on the pinned main	Follow-up question
Flutter / Dart AOT (#1582)	Pure APK parsing; explicit ABI selection; bounded URI/token projection; separate structural and string-pool coverage	Measure a real shipped Flutter app. For snapshot identity/count questions, do unrelated string-pool lists dominate replies? If warranted, reuse opt-in retained views, keep original complete output, exact ABI/target/library identities and lower-bound/partial semantics.
SQLite (#2271)	Compact default schema inventory, exact table/column choices and requested row count; owned snapshot/worker	Verify existing selections on a public real database before adding any selector. Measure large-value/serialization costs and preserve database/WAL identity and 64-bit values.
Recorded packet captures / TShark (#2318)	Explicit fields/filter/decode-as/pass mode; default 50 matching rows; offset/limit/null-complete selection	Compare first versus follow-up pages on public captures. Output paging still dissects the input; investigate repeated work without treating page exhaustion as full capture coverage or silently changing two-pass analysis.
Recorded signals / sigrok (#2339)	Explicit decoder/channel/annotation choices; default 50 display lines; offset/limit/null-complete selection	Measure real upstream recordings and repeated pages. Windows count display lines, not annotations/samples, and still perform decoding. Any future reuse requires clear retained-output ownership and bounded capacity.
Retained unknown heads	Existing opt-in paging preserves the old complete default	Verify representative large investigations and client selection; do not introduce another competing paging API.
Fiddler SAZ (main a2d8b94)	Existing web-capture summary, retained complete/preview pages and archive-member coordinates; all-record decoding before ordinal selection	Measure genuine public SAZ using existing delivery; preserve exact encoded bytes, partial/failure semantics and credential redaction. Real SAZ performance remains unverified here.
aioquic qlog JSON (main bb154d106)	Existing capture summary/pages and qlog views; supported aioquic 1.5.0 / qlog 0.3 JSON; trace-scoped interval unions and endpoint declarations	Measure supported real recordings and existing views. Do not equate endpoint-declared loss with proven network loss, infer recovered bodies or PCAP correlation, or silently accept other layouts. Qlog performance is unverified in the Flutter cohorts.
Frida / attached IDA / live runtimes	Existing target/authority/ownership boundaries remain in force	Separate passive/static efficiency work from execution/injection. No new runtime authority, automatic target launch, provider fallback or GUI database mutation is part of this continuation.

First bounded experiment: official LocalSend 1.18.2 arm64 Android APK, release asset SHA-256 82ec3568fba2aa5295b9aae8b76f701d7a4703d86b9f8bad749472038fbaeab3, 46,558,706 bytes, from the official release. Analyze bytes only; do not execute the APK. The existing frozen runtime 28c84e78cf2fbfde4aceed345b773c59eb889f68 has byte-identical production source to this main pin, so baseline receipts retain that actual runtime revision and digest rather than being relabeled.

Proceed from measurement to one justified change, then repeat equivalent real SDK and Codex tasks. A smaller response alone does not establish lower model tokens, latency, CPU or memory. Do not duplicate SQLite/packet/signal selectors that already exist, introduce generic plugin/cache infrastructure, silently change full defaults, or fix unrelated REA defects. New unrelated findings remain in the separate /tmp handoff.

Continuation acceptance:

• Record bounded real-artifact baseline, source/runtime/provider identity, requested facts and costs for the selected new lane.
• Justify the smallest implementation from observed cost; preserve old requests/full defaults, caller choices, partial facts, Evidence identity and owned cleanup.
• Verify retained/portable reads and affected schema/CLI/MCP boundaries, distinguishing fixtures from real application evidence.
• Repeat actual model/task comparisons with total/cached/uncached input, output, time, errors and quality; retain regressions and failed attempts.
• Commit/push source and curated evidence, review exact-head CI and merge only after verification. Anonymous author email and requested co-author trailer remain mandatory; no release/deployment.

All heavy local work stays serial under one CPU, unchanged 3 GiB early-stop / 4 GiB hard memory / no swap and owned task scopes. Kernel payload-phase observations remain distinct from unavailable whole-scope final counters. Downloaded binaries, raw replies/models and configuration stay private outside Git.

The selected Flutter lane verifies real LocalSend SDK pairs, previous-runtime complete defaults/portable Evidence and four factually correct Codex answers. Detailed paired results retain failed/repeated attempts and unknown final counters. Total input falls 48.75% / 42.38%, uncached input 33.63% / 42.52%, and task time 23.95% / 30.30%; SDK bytes fall 92.05% while SDK workflow time is approximately unchanged. These are one app/question/configuration results, not all-domain completion.

Latest-main Flutter continuation completed (2026-10-13)

Flutter delivery implemented in #2455, commit 23de4f77c74dd299d45cab880c36321d802b21fe.

The five continuation acceptance items above are complete for the selected Flutter lane. Curated LocalSend SDK/model/migration measurements preserve exact frozen pins, all attempts, cached/uncached usage and unknown final resource counters. Reply bytes fall 92.05%; both actual Codex pairs pass selected factual checks with 42.38–48.75% less total input, 33.63–42.52% less uncached input, and 23.95–30.30% less task time. SDK workflow time stays approximately unchanged. These are one app/question/configuration results including actual model retries/repeated calls, not universal or engine-speed claims.

Real Flutter compatibility checks preserve complete/summary SDK facts, all 2,716 original strings through 15 old-Evidence continuation calls with the APK absent, and unchanged CLI complete facts/subject/parameters/ID. The integration runtime file-table digest is 614e687629c8b92424fa33e655848bde92922c40c7dd6953bff6af2d10c61961. These migration checks remain separate from the frozen model measurements and unknown terminal resource counters.

SQLite/QGIS and compact-PCAP continuations are complete, with recorded no-new-API decisions. Larger/non-HTTP TShark, sigrok, SAZ, qlog, retained investigation paging and remaining coverage planning are tracked in the follow-up issues below. Plugin SDK and cross-session engine reuse remain demand-gated research. Original acceptance evidence and the gradual compatibility-first migration plan remain intact.

Next real-data round: verify existing controls before adding code (2026-10-13)

Explore carefully: if measurements do not establish a useful improvement, do not implement another optimization. This SQLite round is pinned to main 172407787f1842dedbcd27b5385177595f786ce4 and makes no real-Windows performance claim.

Re-check existing SQLite, packet/signal and SAZ/qlog selectors. SQLite already defaults to compact inventory and exposes exact table/column and schema-scope choices; unselected cells are not evaluated/projected. Packet/signal tools already expose fields/annotations and output windows. SAZ/qlog already have retained summary/page ownership. Do not duplicate these controls or introduce a cache merely because it could exist.

First real target: QGIS's shipped world-map GeoPackage, from immutable official source commit e1223b8e9e71fc50ee995ed556f711c54ccc101b, 12,914,688 bytes, Git blob c9ff80228dff0de93c9acdef16a97545ba360244, SHA-256 01d293159d1b77bd9212b5252587853f61aa9e25b2387135f34afaba8d057190. Official asset and upstream provenance. Downloaded bytes match the upstream Git blob. This is actual application data, not a generated REA fixture; QGIS is not installed or executed.

Compare the same requested SQLite row facts through public REA CLI/MCP: table default/all-visible columns versus existing exact columns, then compact inventory scope when it still answers the question. Keep the same row limit and preserve typed 64-bit integers, exact text bytes, SQL NULL, database/WAL identity, engine identity, original limitations and explicit unspecified/truncated row order. Preserve both original schemas; scope differences are not silently erased. Fresh process state is distinguished from host page caching. If source projection changes observed row order, record it rather than claiming equivalent samples.

If SDK results justify a treatment, repeat actual Codex CLI tasks with the same question and tool set, requested gpt-5.6-terra high, isolated temporary configuration and measured REA runtime. Report total/cached/uncached input, output, whole-task time, failed/repeated calls and factual quality. Fewer reply bytes alone are not a model-token or speed result. Keep negative/no-benefit findings and avoid production/API edits if existing controls suffice.

Round acceptance:

• Record actual current-main/corpus/runtime identities, existing controls and real-artifact baseline.
• Compare equivalent selected facts and preserve original scope, precision, provenance, source bytes and relevant CLI/MCP contracts.
• Repeat justified real-model comparisons with all attempts and honest token/time/resource scope; explicitly record no-benefit results.
• Record the evidence-led decision (including no production change), commit/push useful reproduction/curated findings, and verify any resulting PR before normal merge; no release.

Unchanged safeguards: heavy work serial, one CPU, 3 GiB early stop / 4 GiB hard memory, no swap, owned task scopes and host-availability checks. Payload observations do not certify missing final whole-scope counters. Raw binaries/replies/model traces/configuration remain private outside Git. Unrelated REA defects are handed off in /tmp/rea-analysis-efficiency-bugs-20261012.md, not fixed in this round. Other domains remain incremental, not claimed complete.

SQLite round result: existing controls suffice

No production/API, default, provider annotation, SDK or cache change is justified. The current shipped tool already preserves full selected-table schema while columns: ["fid", "NAME", "ISO_A3"] avoids unrelated geometry values. QGIS SDK replies fall from 485,277 to 18,509 bytes (about 96.2%). Both paired selected-fact comparisons pass; full SQL/schema/null/tagged sample facts and database/WAL/engine identity remain intact. SDK time and CPU do not improve: selected workflows are slower in these observations, and timings vary substantially. Keep those results rather than crediting bytes as speed.

Four corrected actual Codex trials (requested gpt-5.6-terra high, one exact enabled tool, same frozen main runtime) pass every selected fact and cleanup check. Total input falls 57.63% / 36.44%, uncached 54.14% / 44.08%. Time is mixed: 4.17% slower / 14.39% faster; output 10.77% lower / 6.94% higher. Actual repeated calls stay counted (all=2/2, columns=1/2). This supports scoped existing-selector token savings, not a stable speedup or a new mechanism.

The initial four model calls were blocked by the isolated client's approval policy and have no SQLite result; all factual grades fail. The experiment driver now uses its existing exact per-tool approval entry for SQLite while exposing only that selected tool. Corrected cohorts are separate; original failures and costs remain retained. No global Codex configuration or REA authority/annotation is changed.

Actual CLI inventory/all/columns results, subjects, caller parameters and IDs equal corresponding complete MCP records; original bytes remain unchanged. Independent read-only SQLite 3.40.1 binding agrees with exact table SQL, eight declared columns and tagged sample. Six existing context/driver tests, Python compilation and JS syntax checks pass. Missing terminal whole-scope counters remain unknown; narrower payload observations verify cleanup and phase events.

Existing SQLite documentation and skill guidance already recommend column selection; the measured result does not justify a redundant product change. Other domain lanes remain incremental.

SQLite round completed — PR #2489

SQLite experiment #2489 merged as 45984a4319c8b6dcf2b03e969fbd4330c8432394. The change is confined to seven experiment files; production implementations, APIs and complete defaults are unchanged.

SQLite measurements remain pinned to main 172407787f1842dedbcd27b5385177595f786ce4. Real CLI/MCP parity and independent read-only SQLite access agree on the requested schema/cells. Subsequent SDK compatibility checks preserve selected facts and source bytes without extending the model-performance scope.

The SQLite factual grader distinguishes missing from explicit null and preserves exact JSON scalar types. All four stored model answers pass; omitted wal and boolean row_limit mutations fail. Original blocked trials, transcripts and usage remain private and intact; review fixes do not rerun models.

Decision remains use existing controls; no new production optimization. SDK reply bytes fall about 96.2%; actual total model input falls 57.63% / 36.44%, uncached input 54.14% / 44.08%. SDK time/CPU show no improvement and model time remains mixed (4.17% slower / 14.39% faster). These are QGIS/schema-and-sample observations, not universal speed or memory claims. Resource controls remain one CPU, 3 GiB early stop / 4 GiB hard memory and no swap; unavailable final whole-scope counters remain unknown.

All four acceptance items for this round are complete. Other packet/signal, SAZ/qlog and application/platform questions remain incremental evidence-led follow-ups; continuations are tracked in separate issues below. No unrelated REA product bug was identified in this round.

Packet-capture real-data round (2026-10-13)

Main is pinned to 3ae826ceba6f25b08bce50bcb51001209bc16b57, with 23 post-SQLite commits, including bounded PCAP summaries/retained pages, authenticated artifact subjects, unknown-snapshot reuse and shared transcript grading. The new PCAP family already exposes complete defaults plus opt-in summary/pages; do not duplicate it. Existing selected-field TShark inspection remains a separate analyst boundary, not an interchangeable complete-inventory claim. Work is isolated in perf/2016-packet-real-data-20261013.

First targets are the unmodified HTTP request/response and HTTP redirects recordings published on the official Wireshark sample-capture page. Pin downloaded sizes/digests and original URLs; do not claim an independently published upstream digest where none is supplied. These are saved captures, not newly acquired traffic or executions of recorded targets.

Fix one question: complete capture identity/metadata, all observed and retained inventory counts, source coverage/limitations, and the first two retained HTTP URIs in original order. Compare existing complete inline delivery with summary plus an exact retained URI page on the same frozen runtime. Extra RPC/schema/retry costs remain counted; an exhausted URI page does not prove network completeness. Start with small real captures, where extra paging may be a net loss. Use actual CLI/MCP and independent raw capture facts; actual repeated model tasks determine token/time effects when the comparison remains justified. Negative results are useful and do not justify changing defaults or adding production mechanisms.

• Pin runtime/corpora and inspect actual live contracts before measurements.
• Compare equivalent selected facts through real complete and summary/page workflows; preserve original replies and independent validation.
• Record completed-task token/time/CPU/memory evidence, failed/repeated calls, and justified unverified scope.
• Make the evidence-led decision, save useful reproduction/results, and verify any PR before normal merge; no release.

Resource controls remain unchanged: serial heavy work, one CPU, 3 GiB early stop / 4 GiB hard memory, no swap and owned scopes. New providers or target execution/mutation are outside this round. Raw captures, replies, model traces and temporary profiles remain private. Unrelated REA defects go to /tmp/rea-analysis-efficiency-bugs-20261012.md for team follow-up, not fixes here.

Small-PCAP result: complete delivery wins on total input

Two unchanged official Wireshark recordings are pinned: HTTP http.cap, 25,803 bytes / SHA-256 25a72bdf10339f2c29916920c8b9501d294923108de8f29b19aba7cc001ab60d; redirects http_redirects.pcapng, 47,804 bytes / SHA-256 ff432a6b71d06cd20720f7763e584014edd0a43c3b55981c682d1b7640207abc. Local hashes pin downloaded bytes; upstream independently published digests remain unknown. Frozen main runtime file-table SHA-256 is db050545e94dc305a48042e06df96ac6c64b21ee6c5c4707c787d5e46df79e47, Linux/Node 24.18.0, SDK 2.3.1, actual Wireshark 4.0.17.

Eight real SDK trials (complete/summary/summary/complete per recording) match selected metadata/counts/URI facts, settings and source bytes. Original delivery limitations/IDs/source-versus-page coverage remain retained separately. Complete replies are 7,601 / 7,535 bytes; summary plus a URI page totals 17,540 / 17,240 bytes. All four SDK pairs are slower and consume more payload CPU; memory is mixed. Fewer bytes are not inferred as tokens.

Four actual Codex CLI 0.161.0 tasks (requested gpt-5.6-terra high, same question/runtime/providers/two enabled tools) all pass selected facts. Complete input is 38,947 / 38,917; summary/page input 58,779 / 58,584: total input increases 50.92% / 50.54%. Output increases 52.95% / 51.48%. Uncached input is mixed, 28.75% lower / 28.74% higher; time is mixed, 103.41% slower / 52.37% faster. Cached input stays included in totals; actual reasoning/output and all calls are retained. No extra/repeated/failed MCP call occurs. Original bytes and all temporary-profile cleanup checks pass. No caching/time cause is inferred.

The initial summary grade rejected equivalent explicit labels and a URI object carrying correct page/source coverage; this was an experiment-grader representation issue, not incorrect model facts or a REA defect. The grading boundary now accepts those known forms while rejecting omissions, wrong types, contradictory duplicates, false page exhaustion and unsupported claims. Original reviews/source/answers remain intact; no model is rerun. Nine context/grading regressions and four mutations of a real stored answer pass their intended positive/negative checks.

Independent stdlib raw PCAP/PCAPNG/Ethernet/IP/TCP/HTTP-header parsing agrees on 43/271 packets, endpoint counts, URI prefixes and 2/23 distinct HTTP URIs, without invoking Wireshark. DNS associations, protocol-stack dissection and nullable timestamps are not independently validated. Both actual CLI complete results match full MCP result/subject/parameters/ID/limitations; portable CLI summary/page normalized facts and subjects match MCP retained views, preserving distinct caller/source forms.

Decision: no production optimization. Keep complete defaults and existing explicit choices. These compact captures and this question do not justify a new API, automatic summary switch, plugin layer or cache. Larger captures, other protocols/platforms and model workloads remain incremental/unverified.

Heavy work remains serial under one CPU, 3 GiB early stop / 4 GiB hard memory and no swap. Build peak is 2,575,732,736 bytes; payload cleanup/zero phase limit events are verified. Missing terminal whole-scope counters remain unknown and strict resource grades false. Raw captures/results/traces/config remain private. No unrelated product defect is identified or fixed; no release is performed.

PCAP experiment acceptance and completed decision

PR #2640, commit c7105d9723c835b5e0122f5fc6cfbea86265c349, preserves the negative compact-PCAP result. Curated corpus, source/runtime pins, measurements and reproduction. Final scope is nine experiment files and one discovered evaluation test; production APIs/defaults/cache are unchanged.

SDK acceptance authenticates complete/summary/page Evidence through the pinned runtime's existing parser. It preserves subject/path/digest, exact requested facet/range/coverage and JSON scalar values, producer/tool/operation ownership, unique reply IDs and linked retained-parent ID/digest. Present normalized limitations/unknowns must be string arrays; absence and valid empty arrays remain distinct. Legitimate summary delegation is preserved.

Factual and exact-workflow grading are separate. Workflow acceptance requires the planned ordered calls/arguments, successful readable replies and exact citation cardinality. Failed or malformed replies retain diagnostics and supported partial facts. Synthetic fixtures and consumer fault injections establish acceptance guards, not real-provider malformed behavior.

All 18 original SDK/model receipts authenticate. Thirty-four context/grading regressions, six discovered comparator scenarios and all four stored model answers pass their recorded checks without model reruns. The comparator uses the existing evaluation project; the duplicate manual suite is removed. Original bytes/tokens/timers and runtime 3ae826ceba6f25b08bce50bcb51001209bc16b57 remain unchanged.

Decision: for these two compact HTTP captures and the fixed metadata/URI question, summary/page total input worsens about 51% in both pairs; keep existing complete defaults. Other question/domain results are not inferred from this corpus.

Future bounded comparisons may use existing protocol/field discovery to select exact fields on real non-HTTP captures, counting discovery/schema/RPC/retry costs and preserving provider-specific field identity. Larger captures, signal, SAZ/qlog and application questions remain unmeasured lanes. Plugin SDK and cross-session engine caching remain deferred. Further opportunities are tracked in the separate issues listed below.

Originally created by @N0zoM1z0 on GitHub (Oct 12, 2026). Original GitHub issue: https://github.com/morluto/rea/issues/2016 Originally assigned to: @N0zoM1z0 on GitHub. ## Outcome Improve end-to-end REA investigation efficiency while preserving the working CLI/MCP workflows of existing users. Implement three increments in this order: 1. Measure the actual costs and improve known nested result types and caller-selected Evidence views. 2. Evaluate explicit, task-verified Ghidra analysis presets using the existing analyzer controls. 3. Pilot a small, statically composed domain-module descriptor for WASM or EVM, without introducing a general plugin ecosystem. This is a concrete implementation and real-artifact verification follow-up to #740 and #1065. Those issues remain the owners of their broader architecture and performance roadmaps. Evidence lifetime design remains associated with #721; real demonstration coverage is related to #778. The study starts from frozen main `42b0ed126df7d5b908ac369715378d5e519051b7` (2026-10-12 UTC). Each experiment records its own immutable runtime/corpus/provider pins; later integrations do not relabel the original measurements. Version publication and deployment remain outside this work. ## Completion review — 2026-10-14 The original three increments are complete within their recorded scope: measured costs and typed opt-in result delivery; task-scoped Ghidra profile evaluation/lifecycle verification with unchanged defaults; and static WASM/EVM descriptor pilots with exact contracts and retained cleanup ownership. All 34 listed acceptance items have recorded evidence, and all 15 related implementation/experiment PRs are merged and present in main `f3534749e564421036ac445f536fc766b038208f`. Measured decisions remain task-specific. Flutter/LocalSend's two actual model pairs reduce total input by 42.38–48.75% and task time by 23.95–30.30%. QGIS SQLite's existing column selection reduces total input by 36.44–57.63%, with mixed task time and no new API. Compact HTTP PCAP summary/page increases total input by 50.54–50.92%, so complete defaults remain the appropriate choice for that question. Descriptor wiring itself is not a token/speed improvement, and reduced Ghidra analysis lost callee facts, so no general fast preset is recommended. CPU/memory safeguards and phase measurements do not establish universal resource savings or verified unavailable terminal counters. Additional protocols/artifacts/hosts, general plugin SDK/ABI admission, and persistent cross-session engine caches are optional follow-up work rather than unfinished requirements of the original scope. Existing-user and old-Evidence compatibility are supported by the pinned invocations and migration checks; every historical client/platform is not claimed verified. This review reconciles implementation and preserved evidence; it does not rerun the full real-model/provider matrix. The original scope is closed as completed; further measured opportunities are owned by the separate issues listed below. ## Follow-up handoff — 2026-10-14 **Closed as completed:** all 34 recorded acceptance items for #2016 have scoped evidence, and its 15 related implementation/experiment PRs are merged. The original design, immutable measurement pins, positive/negative findings and compatibility qualifications remain here as the completed record. Creating the independent follow-ups does not reopen the original scope or claim new performance results. | Follow-up | Issue | Completion boundary | | --- | --- | --- | | Larger/non-HTTP captures | [#3130](https://github.com/morluto/rea/issues/3130) | Existing discovery/field/filter controls, repeated dissection and real token/time comparisons | | Recorded signals | [#3131](https://github.com/morluto/rea/issues/3131) | Decoder/channel/annotation selection and repeated display-page costs | | SAZ archives | [#3132](https://github.com/morluto/rea/issues/3132) | Existing summary/retained transaction views on genuine public recordings | | Qlog recordings | [#3133](https://github.com/morluto/rea/issues/3133) | Supported trace/event/summary workflows with truthful declared-event semantics | | Large retained investigations | [#3134](https://github.com/morluto/rea/issues/3134) | Existing paging, producer reuse and authentic old-Evidence continuation | | Remaining real-artifact/provider gaps | [#3135](https://github.com/morluto/rea/issues/3135) | Bounded planning: rank at most three precise next pilots, not an all-domain benchmark | | Ghidra engine reuse — research gate | [#3136](https://github.com/morluto/rea/issues/3136) | Establish demand and measured benefit beyond existing snapshots/#1048 before any persistent cache | | External modules — research gate | [#3137](https://github.com/morluto/rea/issues/3137) | Establish concrete demand and compatibility criteria before an SDK/loader/ecosystem | All eight follow-ups carry exactly the same labels as #2016 (`enhancement`, `P1: high`, `area: domain`, `roadmap`, `performance`, `design`) and are assigned to `N0zoM1z0`. Each contains its own analyst question, bounded work, evidence/acceptance contract and compatibility/resource constraints. Broader roadmaps remain with #740/#1065; existing feature owners are linked rather than duplicated. Start with #3130 for the next measured capture round; #3136/#3137 are demand-gated research, not an instruction to implement caches or a plugin ecosystem. Relevant experimental decisions belong in their new owning issue. PR-specific CI/review/rebase progress belongs in the corresponding PR; unrelated product defects remain in the local team handoff. Existing controls may be sufficient, and a well-supported no-change or unavailable conclusion completes the relevant research task. ## Optimization priorities and progressive migration The two primary objectives are **agent token consumption** and **end-to-end task time**. Memory and CPU consumption are also optimization objectives and remain bounded throughout experimentation. Correctness, meaningful Evidence/coverage, caller choices, and compatibility for existing users are acceptance conditions: a smaller or faster incomplete answer is not an improvement for the same question. | Objective | What to measure and optimize | Interpretation boundary | | --- | --- | --- | | Agent tokens — primary | Necessary model-visible facts and useful provenance; discovery context; total/cached/uncached input and output; calls, retries, errors, and follow-up turns for the same analyst question | Avoid overwhelming the agent with unrelated bulk data. Compact JSON byte reduction is a delivery result, not an exact token reduction. A smaller response must still let the agent answer the question. | | Task time — primary | Time to a factually acceptable answer, including provider startup/analysis, transport, client processing, model turns, and corrections; separate cold/warm conditions and observable stages | Fewer bytes or one favorable model trial does not establish a general speedup. Repeat comparable trials before extending a claim. | | Memory | Aggregate process-tree peak/limit events; retained Evidence; object/serialization expansion; worker/engine usage; verified cleanup | Preserve host safeguards and no-OOM operation; moving allocation between processes is not proof of lower aggregate memory. | | CPU | Aggregate CPU time needed to complete the same question, plus observed stage timings where available | The one-CPU quota is an experiment control, not a demonstrated CPU saving. A shorter wall time is not automatically lower CPU work. | Prefer explicit, focused result delivery and reuse of retained Evidence where these preserve the requested facts. Keep existing complete requests available and unchanged. Do not silently reduce engine analysis, truncate Evidence, change source selection, or change a caller's provider to improve a metric. **Verification and migration are progressive.** Extend the domain matrix one bounded step at a time, with real shipped artifacts for the changed domain and relevant shared-contract regression checks. Completing every advertised domain in one pass is not required. Native Windows PE and original UPX-compressed DOS MZ have been statically verified through Linux Ghidra in #2216. Native Windows runtime behavior, unpacked DOS editor logic and DOS COM remain unverified; managed PE/CLI does not substitute for native PE. Firmware region inspection, selected JavaScript AST analysis, and browser capture each retain their stated narrower coverage. Preserve unavailable and incomplete outcomes rather than treating them as global successes. Compatibility directions are explicit: - **Existing clients / new REA:** existing names, accepted arguments, complete defaults, provider choices and session semantics must continue to work. The current pilot is additive and opt-in; existing users need no new pack or request rewrite to retain shipped capabilities. - **Existing Evidence / new REA:** preserve authenticated original records and IDs during import, inline use, new views and export. Actual baseline SQLite/Obsidian migration is recorded in the linked checkpoint. - **New capabilities / older REA:** clients must discover the actual advertised schema and use supported existing equivalents where available. Older servers do not automatically understand the newly added selectors. A universal automatic fallback is not implemented or claimed by this study. The current evidence is pinned to the recorded baseline, clients and real workflows; it is not an unconditional guarantee for every historical release, OS or third-party integration. The earlier `259e99dd9` runtime grows the complete catalog about 2.6% in compact JSON; the later main-integrated runtime records about 1.4% growth versus the original baseline, including intervening main changes. Keep this discovery cost visible alongside selected-delivery savings. Existing complete requests do not automatically receive the new token-saving delivery path. Newly found REA bugs remain documented locally for later team repair, as requested. ## Evidence motivating the sequence The previous optional Code Mode experiment is pinned at [`e65a13f54`](https://github.com/morluto/rea/commit/e65a13f54d0138537c07b6e791c7176e0aa0fa30), using the earlier frozen production baseline `fb94d9dde0ccda83ae520ac6fb22b1d283562cf3`. - [Decision and migration boundaries](https://github.com/morluto/rea/blob/e65a13f54d0138537c07b6e791c7176e0aa0fa30/experiments/codemode/decision.md) - [Measured cohort and fingerprints](https://github.com/morluto/rea/blob/e65a13f54d0138537c07b6e791c7176e0aa0fa30/experiments/codemode/agent-results.json) - [Results, failed attempts, and verification limits](https://github.com/morluto/rea/blob/e65a13f54d0138537c07b6e791c7176e0aa0fa30/experiments/codemode/results.md) - [Real artifact provenance and digests](https://github.com/morluto/rea/blob/e65a13f54d0138537c07b6e791c7176e0aa0fa30/experiments/codemode/corpus.json) Sixteen serial real Codex CLI trials, configured with `gpt-5.6-terra` high, covered Android, managed PE/CLI, Electron inventory, firmware, and Ghidra native analysis. Twelve passed the requested fact/reference assertions. Two bridge managed answers omitted a classification field; two direct managed JSONL transcripts truncated a producer envelope and prevented complete-envelope reference verification. These are different failure classes, and the stronger complete-classification assertion exceeded the question's general wording. The bridge did not establish a stable overall speedup: - Android bridge repetitions took 48.231 and 134.555 seconds, compared with 67.329 and 71.624 seconds directly. The model did not consistently select one composed execution. - Guided Electron inventory reduced total input from 263,484 to 101,994 tokens, but uncached input only from 41,532 to 40,554; bridge wall time was 85.909 versus 67.540 seconds. Context compression is not equivalent to cost or latency reduction. - Ghidra took 334.642 versus 327.150 seconds with unchanged analysis settings. Provider CPU remained the dominant measured work. - SQLite WASM exposed a frozen WABT row-parser failure. Obsidian full AST analysis timed out with a retained partial reference. Neither is a successful Code Mode result; successful inventory answers do not replace AST analysis. The existing bridge receives complete upstream results before projecting them. It can reduce model-visible data while retaining upstream analysis, serialization, transport, parsing, Evidence, and guest-transfer costs. REA already has typed domain ports, canonical named contracts, provider factories, owned-process primitives, snapshot replay, and retained Evidence views; reuse these rather than rebuilding them. ## Compatibility contract Compatibility is an acceptance condition for each increment, not a final documentation exercise. - Keep the normal distribution usable with its existing capabilities. Existing users must not have to discover and install new packs merely to regain previously shipped tools. - Preserve existing CLI command names, MCP tool names, argument meanings, caller-selected targets/providers/paths, defaults, result fields, structured/text delivery, and tagged failure semantics. - Do not silently narrow the set of supported old inputs while improving producer output typing. - Preserve the default complete-result path. New focused views, module selection, and analysis presets must be explicitly selected; no silent truncation or automatic switch to reduced analysis. - Preserve the default complete and stable tool catalog. Any experimental pack-selection profile is explicit and fixed for that connection; opening a target must not remove tools. - Configuration changes are additive and idempotent, with backups when files are written. Retain existing environment/configuration names and meanings. Do not install or upgrade unrelated host software. - Preserve existing Evidence identity, raw/normalized distinctions, uncertainty, coverage, authority, session retention, and export/import behavior. In particular, do not silently change the default `close_binary` record lifetime. - A derived view receives its own identity and links to its parent Evidence. A caller projection must not masquerade as the original canonical record under the parent's ID. - New clients using new capabilities against older servers must discover actual support and use supported existing operations where an equivalent workflow exists; report unavailable capabilities honestly. Never change a caller's provider choice to create an apparent success. - Use pinned pre-change invocations, configuration fixtures, and actual CLI/MCP clients as compatibility evidence. Pure composition changes should preserve catalog schemas/digests and public behavior; intentional additive schema/view changes require their own consumer checks. ## Target architecture and ownership The diagram below translates and tightens the architecture proposal. Solid arrows describe interface dependencies or provider execution; dashed arrows describe explicit production composition. Domain and application contracts do not import engine protocols. This is a target boundary map, not a proposal to move every file or ship three new package systems at once. ```mermaid flowchart TB subgraph Entry["Existing entry points"] CLI["CLI"] MCP["MCP"] CM["Optional Code Mode client / bridge"] end subgraph Shared["Shared application and domain semantics"] WF["Typed operations and composed workflows"] PORTS["Domain capability ports and canonical contracts"] MODEL["Pure domain models, identity, coverage and error semantics"] EV["Investigation records and Evidence views"] end HOST["Production composition: static module descriptors\nnamed registration, typed factories and cleanup ownership"] AD["Engine adapters: Ghidra, IDA, JADX, WABT and others"] PROC["Owned process, session and resource supervision"] ENGINE["Local engines and artifact readers"] CLI --> WF MCP --> WF CM --> MCP WF --> PORTS WF --> EV PORTS --> MODEL EV --> MODEL AD -->|implements| PORTS AD --> PROC PROC --> ENGINE HOST -. injects .-> WF HOST -. constructs .-> AD HOST -. binds named contracts .-> MCP HOST -. binds existing commands .-> CLI ``` The extension roles remain separate: | Role | Responsibility | Ownership boundary | | --- | --- | --- | | Domain module | Domain schemas, query/view semantics, precise capabilities, and existing registration metadata | Reuses pure models and typed ports; does not own a universal engine protocol | | Engine adapter | Version/support inspection, protocol parsing, analysis implementation, process and target session | Implements applicable ports; owns and cleans up its acquired resources | | Workflow | Compose compatible domain facts to answer a recurring analyst question | Uses typed operations and source Evidence; does not construct duplicate engine sessions | | Composition host | Bind exact contracts to implementations and register acquired resource ownership | Explicit static composition first; preserves healthy peers and failed-cleanup ownership | Existing entry points retain their public behavior. The first descriptor pilot is an internal wiring change. A native and a firmware workflow can share an adapter implementation while still requiring separate Program instances for distinct targets. Reuse of a live instance requires matching target/profile/revision and a single clear owner. Engine sessions and investigation Evidence have different responsibilities, but the first increments preserve the existing record lifetime. They do not silently retain records after `close_binary`; portable export/import is the initial cross-session continuation. ## Increment 1: cost measurement and precise result delivery ### Establish a comparable baseline Record artifact and provider digests, exact revision, operation arguments, analysis settings, CPU/memory limits, client/model configuration, and cold/warm state. Separate: - Engine launch, import, auto-analysis, readiness, and first/warm query where those stages are observable. - Queue wait and provider operation time. - Result assembly, validation, retained Evidence/cache work, serialization, transport bytes, and client parsing/validation where measurable. - Tool discovery, model turns, repeated operations, failures/retries, API token usage, complete task time, and useful answer quality. Add instrumentation at the boundary that owns each measurement. Diagnostic timing must not change canonical Evidence identity or retain an unbounded history. Report unavailable stage measurements explicitly rather than inventing a decomposition from total wall time. ### Improve known nested payloads and selected views Start with `inspect_artifact`'s nested inventory Evidence and the existing `inspect_analysis_view` machinery. Where an operation guarantees a known payload, advertise and validate its concrete nested structure instead of generic JSON. Reuse canonical schemas to derive authoring types and examples. For repeated questions such as manifest, entry-kind counts, and selected root occurrence records, offer the smallest justified caller-selected view, with the selection scope, original identities, coverage, unknowns, limitations, and contributing Evidence links. Retain the complete source record under its existing lifecycle. Repeated views must not re-run the producer. Measure the changed SDK-converted catalog as well as runtime results: a more precise schema can increase discovery size. Validate the declared JSON Schema dialect and actual client calls. View projection after analysis and producer-side query pushdown are separate experiments; do not claim saved engine work from a smaller response alone. Acceptance: - [x] A pinned, reproducible baseline distinguishes measured costs and unknown stages. - [x] Known nested output is validated and discoverable through the actual SDK/client boundary. - [x] Existing full output/defaults and old inputs remain usable. - [x] Focused results preserve meaningful source, selection, uncertainty, and coverage. - [x] Retained follow-up does not re-run the producer and survives relevant partial failures. - [x] Real large-artifact runs show the measured benefits and any regressions, including parsing/serialization and peak memory. ## Increment 2: explicit, task-verified analysis presets Use the existing `REA_GHIDRA_DISABLED_ANALYZERS` support and committed analysis profile. First measure default behavior; then evaluate one narrowly scoped alternative against exactly defined analyst questions. - Keep the default profile unchanged. - Specify engine version, applicable target formats/languages, selected settings, task scope, evidence available, and explicit unknowns. - Measure cold startup/import/analysis and warm query separately; use matching CPU/JVM limits. - Verify the task's necessary facts, not just shorter wall time. Missing xrefs under reduced analysis do not establish their absence. - Keep effective settings in profile/cache identity. Old cached results must not be replayed under a different preset. - If later work introduces incremental analysis, it needs an explicit readiness/analysis revision and coverage commitment. That lifecycle change is not required for this first preset experiment. Acceptance: - [x] Existing default invocations produce compatible behavior. - [x] The selected alternative is verified on real shipped binaries with pinned questions and producer evidence. - [x] Profile differences and limitations are visible; cancellation, failure, cleanup, and snapshot compatibility are covered. Verified in #2349 with actual Linux Ghidra 12.1.4 default/disabled profiles, GNU true and jq snapshot workflows, startup cancellation, invalid-analyzer failure, and permission-induced cleanup retry; this does not imply other OS/provider coverage. - [x] Any performance recommendation is restricted to the tested task/format/provider scope. ## Increment 3: one small domain-module descriptor pilot Choose WASM or EVM based on the refreshed source and provider results. Keep one local distribution and explicit static composition. The descriptor should bind existing exact contracts, typed service/provider factories, adapter registration, availability/effects, and owned cleanup. Preserve compiler checks inside each module and validate unknown values at actual dynamic boundaries. Maintain these ownership rules: - Pure domain data/semantics and typed application ports remain independent of specific provider protocols and CLI/MCP implementations. - Composition constructs implementations and injects them. A module descriptor must not become a provider-specific dependency in core domain code. - Domain, engine, and workflow extensions remain distinct. Complementary Android bytecode/resource/runtime capabilities must not be forced into one interchangeable universal provider interface. - Sharing an engine adapter is not sharing one global Program/session. Reuse requires the correct target, profile, revision, and owner; different targets retain separate mutable analysis state. - Resource registration happens when the module acquires resources. Failed cleanup retains ownership and permits meaningful recovery; unloading must not discard an owned resource merely because close failed. - Optional module failure must preserve healthy peers and disclose the failure. Acceptance: - [x] One domain is wired through its descriptor with fewer independently maintained core registration/cleanup points. - [x] Default catalog, old CLI/MCP inputs/results, provider choices, and lifecycle behavior remain compatible. - [x] Duplicate names and incompatible contracts fail clearly before use. Scoped to the static pilot: #2427 verifies exact operation/CLI/factory/input/output assignability in the complete compiler gate and actual SDK duplicate registration before any provider call. Dynamic third-party ABI/version admission is not introduced; validating unknown provider replies after execution remains a distinct boundary. - [x] Actual CLI/MCP workflows cover unavailable providers, malformed inputs, cancellation, capacity, partial failures, and cleanup retry. Linux x64 real EVMole/prlimit verification from #2261 and #2404, including actual worker replies, late SDK cancellation, permission-induced retained cleanup recovery and a healthy real WABT peer; mid-WASM interruption and other hosts are not claimed. - [x] Packaging and generated projections remain derived from owning source. - [x] The changed architecture is followed by cross-domain real-artifact regression, not only recording-port tests. ## Real-artifact and real-model verification Reuse the previously digest-verified public corpus where suitable, and add public shipped artifacts for uncovered available domains. Keep binaries, provider projects, raw target output, temporary credentials, and local profiles outside Git. Record acquisition URL/version/digest and preserve exact target bytes. | Lane | Initial real artifact / workflow | Required evidence | | --- | --- | --- | | Native | jq 1.8.2; add a larger public binary for preset evaluation | Target identity, known selected procedures/relationships, default versus explicit profile, readiness and cleanup | | Managed PE/CLI | ShareX 19.0.2 assembly | Assembly/module identity, selected members/native boundaries, complete classification and explicit coverage | | Android | NewPipe 0.29.1 APK | Package identity, selected classes/methods, descriptor/null semantics, real JADX results and cleanup | | Electron/package inventory | Obsidian 1.14.4 ASAR | Complete source inventory retained; manifest/counts/selected paths, contradictions, AST unknowns, view parity | | JavaScript/AST | Public shipped JavaScript artifact with a bounded, meaningful static question | Actual producer facts, partial/timeout outcome when applicable, retained continuation; inventory is not an AST substitute | | Firmware | OpenWrt 25.12.5 Archer C7 v5 image | Real Binwalk/Unblob observations where available, offsets/sizes, engine identity, signature-scan coverage | | WASM | SQLite Wasm 3.53.4-build1 | Real pinned WABT output, format-aware parsing, complete/failed coverage and target digest | | EVM | Public deployed bytecode with recorded source provenance | Original carrier and decoded-byte identities, inferred selector/interface facts and unknown authenticity/completeness | | Browser/runtime | A controlled owned browser capture of a real public application when the host supports it | Actual capture/source attribution and owned lifecycle, with explicit runtime authority | Extend this matrix to other advertised domains affected by the composition change. Distinguish an unavailable OS/engine/input lane from a passed real-provider test. Linux results do not prove Windows/macOS, Hopper, IDA GUI, ADB-device, or other unavailable provider behavior. Real application and real-provider success must never be inferred from simulated ports. Run comparable fixed replays first to isolate implementation cost, then use real Codex CLI with temporary isolated configuration pointing to the modified REA MCP. Keep the requested model/configuration explicit; initially reuse `gpt-5.6-terra` high for comparability. Grade requested facts, explicit unknowns, cleanup, and source references against actual producer evidence. Verify per-claim support where feasible, beyond merely seeing a valid ID in a transcript. Save failures, retries, transcript truncation, and timeouts in the results. Separate cold/warm sessions and cache states, interleave pair order, and repeat representative pairs. Record total/cached/uncached input and output separately without treating token totals as currency cost. Claims remain descriptive until the sample supports stronger conclusions. ## Host resource controls - Heavy builds/tests/provider/model trials run serially in owned resource scopes. - Initial aggregate trial limits: one CPU, 4 GiB hard memory ceiling, 3 GiB early-stop threshold, no swap growth, and bounded tasks; refuse starts when host available memory is low. - JVM/Node/worker limits fit within the aggregate budget. Account for object copies, serialization expansion, retained Evidence/cache, and temporary disk before increasing concurrency. - Record sampled family memory/tasks, CPU usage, resource-limit events, timeout/abort reasons, and owned cleanup. A limit event invalidates a purported successful performance run. - Delete disposable model profiles and copied authentication material on success, failure, cancellation, and timeout. Do not capture the ambient environment. - Do not kill processes using a PID alone or touch user-owned GUI databases. Preserve owned resources whose cleanup is unverified. ## Deferred decisions General third-party plugin SDK/distribution, automatic plugin discovery/hot reload, cross-session Ghidra database persistence, and broad shared-query concurrency are deferred until actual demand or measured repeated work justifies their compatibility and lifecycle costs. Code Mode remains optional; this issue does not switch existing users to the external bridge. ## Completion evidence - [x] Commit the implementation, relevant compatibility/boundary tests, source-authored documentation, and curated measurements. - [x] Run appropriate source, focused artifact, typecheck/lint, schema, generated-doc, packaging, and real-provider checks for the touched boundaries. - [x] Repeat the available real-domain matrix against the modified runtime after the descriptor integration. - [x] Publish a final issue update linking commits and describing what changed, measured outcomes, compatibility evidence, failed attempts, and unverified lanes. - [x] Push progress to the implementation branch and create the explicitly requested review PR (#2122); the maintainer subsequently authorized a verified merge and continued work; version publication and deployment remain unauthorized. ## Experiment record ownership (2026-10-12) Detailed generated result JSON is archived byte-for-byte outside the checkout and excluded from the final PR tree. Source-owned corpus inputs, reproduction scripts, measured findings, frozen revision/digest references, compatibility qualifications remain in [the experiment notes](https://github.com/morluto/rea/blob/ae291b4d836722503afbe73841955724cc0e1023/experiments/analysis-efficiency/README.md). Historical checkpoint commits remain intact. ## Latest-main continuation: newer capability efficiency audit (2026-10-13) The refreshed main pin is `f254f5ac2b804b353a711264bb178f43fdf07867`, unchanged since the preceding Android merge. This continuation audits features added during the earlier implementation cycle that were not all included in its final performance matrix; it does not claim new commits after that merge. Work is isolated on `perf/latest-main-efficiency-20261013` in a fresh worktree. Original completed acceptance evidence remains intact. | Capability | Existing delivery/ownership controls on the pinned main | Follow-up question | | --- | --- | --- | | Flutter / Dart AOT (#1582) | Pure APK parsing; explicit ABI selection; bounded URI/token projection; separate structural and string-pool coverage | Measure a real shipped Flutter app. For snapshot identity/count questions, do unrelated string-pool lists dominate replies? If warranted, reuse opt-in retained views, keep original complete output, exact ABI/target/library identities and lower-bound/partial semantics. | | SQLite (#2271) | Compact default schema inventory, exact table/column choices and requested row count; owned snapshot/worker | Verify existing selections on a public real database before adding any selector. Measure large-value/serialization costs and preserve database/WAL identity and 64-bit values. | | Recorded packet captures / TShark (#2318) | Explicit fields/filter/decode-as/pass mode; default 50 matching rows; offset/limit/null-complete selection | Compare first versus follow-up pages on public captures. Output paging still dissects the input; investigate repeated work without treating page exhaustion as full capture coverage or silently changing two-pass analysis. | | Recorded signals / sigrok (#2339) | Explicit decoder/channel/annotation choices; default 50 display lines; offset/limit/null-complete selection | Measure real upstream recordings and repeated pages. Windows count display lines, not annotations/samples, and still perform decoding. Any future reuse requires clear retained-output ownership and bounded capacity. | | Retained unknown heads | Existing opt-in paging preserves the old complete default | Verify representative large investigations and client selection; do not introduce another competing paging API. | | Fiddler SAZ (main a2d8b94) | Existing web-capture summary, retained complete/preview pages and archive-member coordinates; all-record decoding before ordinal selection | Measure genuine public SAZ using existing delivery; preserve exact encoded bytes, partial/failure semantics and credential redaction. Real SAZ performance remains unverified here. | | aioquic qlog JSON (main bb154d106) | Existing capture summary/pages and qlog views; supported aioquic 1.5.0 / qlog 0.3 JSON; trace-scoped interval unions and endpoint declarations | Measure supported real recordings and existing views. Do not equate endpoint-declared loss with proven network loss, infer recovered bodies or PCAP correlation, or silently accept other layouts. Qlog performance is unverified in the Flutter cohorts. | | Frida / attached IDA / live runtimes | Existing target/authority/ownership boundaries remain in force | Separate passive/static efficiency work from execution/injection. No new runtime authority, automatic target launch, provider fallback or GUI database mutation is part of this continuation. | First bounded experiment: official LocalSend 1.18.2 arm64 Android APK, release asset SHA-256 `82ec3568fba2aa5295b9aae8b76f701d7a4703d86b9f8bad749472038fbaeab3`, 46,558,706 bytes, from [the official release](https://github.com/localsend/localsend/releases/tag/v1.18.2). Analyze bytes only; do not execute the APK. The existing frozen runtime `28c84e78cf2fbfde4aceed345b773c59eb889f68` has byte-identical production source to this main pin, so baseline receipts retain that actual runtime revision and digest rather than being relabeled. Proceed from measurement to one justified change, then repeat equivalent real SDK and Codex tasks. A smaller response alone does not establish lower model tokens, latency, CPU or memory. Do not duplicate SQLite/packet/signal selectors that already exist, introduce generic plugin/cache infrastructure, silently change full defaults, or fix unrelated REA defects. New unrelated findings remain in the separate `/tmp` handoff. Continuation acceptance: - [x] Record bounded real-artifact baseline, source/runtime/provider identity, requested facts and costs for the selected new lane. - [x] Justify the smallest implementation from observed cost; preserve old requests/full defaults, caller choices, partial facts, Evidence identity and owned cleanup. - [x] Verify retained/portable reads and affected schema/CLI/MCP boundaries, distinguishing fixtures from real application evidence. - [x] Repeat actual model/task comparisons with total/cached/uncached input, output, time, errors and quality; retain regressions and failed attempts. - [x] Commit/push source and curated evidence, review exact-head CI and merge only after verification. Anonymous author email and requested co-author trailer remain mandatory; no release/deployment. All heavy local work stays serial under one CPU, unchanged 3 GiB early-stop / 4 GiB hard memory / no swap and owned task scopes. Kernel payload-phase observations remain distinct from unavailable whole-scope final counters. Downloaded binaries, raw replies/models and configuration stay private outside Git. The selected Flutter lane verifies real LocalSend SDK pairs, previous-runtime complete defaults/portable Evidence and four factually correct Codex answers. [Detailed paired results](https://github.com/morluto/rea/issues/2016#issuecomment-6137329834) retain failed/repeated attempts and unknown final counters. Total input falls 48.75% / 42.38%, uncached input 33.63% / 42.52%, and task time 23.95% / 30.30%; SDK bytes fall 92.05% while SDK workflow time is approximately unchanged. These are one app/question/configuration results, not all-domain completion. ### Latest-main Flutter continuation completed (2026-10-13) Flutter delivery implemented in [#2455](https://github.com/morluto/rea/pull/2455), commit `23de4f77c74dd299d45cab880c36321d802b21fe`. The five continuation acceptance items above are complete for the selected Flutter lane. [Curated LocalSend SDK/model/migration measurements](https://github.com/morluto/rea/blob/23de4f77c74dd299d45cab880c36321d802b21fe/experiments/analysis-efficiency/flutter-aot-summary.md) preserve exact frozen pins, all attempts, cached/uncached usage and unknown final resource counters. Reply bytes fall **92.05%**; both actual Codex pairs pass selected factual checks with **42.38–48.75% less total input**, **33.63–42.52% less uncached input**, and **23.95–30.30% less task time**. SDK workflow time stays approximately unchanged. These are one app/question/configuration results including actual model retries/repeated calls, not universal or engine-speed claims. Real Flutter compatibility checks preserve complete/summary SDK facts, all 2,716 original strings through 15 old-Evidence continuation calls with the APK absent, and unchanged CLI complete facts/subject/parameters/ID. The integration runtime file-table digest is `614e687629c8b92424fa33e655848bde92922c40c7dd6953bff6af2d10c61961`. These migration checks remain separate from the frozen model measurements and unknown terminal resource counters. SQLite/QGIS and compact-PCAP continuations are complete, with recorded no-new-API decisions. Larger/non-HTTP TShark, sigrok, SAZ, qlog, retained investigation paging and remaining coverage planning are tracked in the follow-up issues below. Plugin SDK and cross-session engine reuse remain demand-gated research. Original acceptance evidence and the gradual compatibility-first migration plan remain intact. ## Next real-data round: verify existing controls before adding code (2026-10-13) Explore carefully: if measurements do not establish a useful improvement, do not implement another optimization. This SQLite round is pinned to main `172407787f1842dedbcd27b5385177595f786ce4` and makes no real-Windows performance claim. Re-check existing SQLite, packet/signal and SAZ/qlog selectors. SQLite already defaults to compact inventory and exposes exact table/column and schema-scope choices; unselected cells are not evaluated/projected. Packet/signal tools already expose fields/annotations and output windows. SAZ/qlog already have retained summary/page ownership. Do not duplicate these controls or introduce a cache merely because it could exist. First real target: QGIS's shipped world-map GeoPackage, from immutable official source commit `e1223b8e9e71fc50ee995ed556f711c54ccc101b`, 12,914,688 bytes, Git blob `c9ff80228dff0de93c9acdef16a97545ba360244`, SHA-256 `01d293159d1b77bd9212b5252587853f61aa9e25b2387135f34afaba8d057190`. [Official asset](https://github.com/qgis/QGIS/blob/e1223b8e9e71fc50ee995ed556f711c54ccc101b/resources/data/world_map.gpkg) and [upstream provenance](https://github.com/qgis/QGIS/blob/e1223b8e9e71fc50ee995ed556f711c54ccc101b/resources/data/README_world_map.md). Downloaded bytes match the upstream Git blob. This is actual application data, not a generated REA fixture; QGIS is not installed or executed. Compare the same requested SQLite row facts through public REA CLI/MCP: table default/all-visible columns versus existing exact columns, then compact inventory scope when it still answers the question. Keep the same row limit and preserve typed 64-bit integers, exact text bytes, SQL NULL, database/WAL identity, engine identity, original limitations and explicit unspecified/truncated row order. Preserve both original schemas; scope differences are not silently erased. Fresh process state is distinguished from host page caching. If source projection changes observed row order, record it rather than claiming equivalent samples. If SDK results justify a treatment, repeat actual Codex CLI tasks with the same question and tool set, requested gpt-5.6-terra high, isolated temporary configuration and measured REA runtime. Report total/cached/uncached input, output, whole-task time, failed/repeated calls and factual quality. Fewer reply bytes alone are not a model-token or speed result. Keep negative/no-benefit findings and avoid production/API edits if existing controls suffice. Round acceptance: - [x] Record actual current-main/corpus/runtime identities, existing controls and real-artifact baseline. - [x] Compare equivalent selected facts and preserve original scope, precision, provenance, source bytes and relevant CLI/MCP contracts. - [x] Repeat justified real-model comparisons with all attempts and honest token/time/resource scope; explicitly record no-benefit results. - [x] Record the evidence-led decision (including no production change), commit/push useful reproduction/curated findings, and verify any resulting PR before normal merge; no release. Unchanged safeguards: heavy work serial, one CPU, 3 GiB early stop / 4 GiB hard memory, no swap, owned task scopes and host-availability checks. Payload observations do not certify missing final whole-scope counters. Raw binaries/replies/model traces/configuration remain private outside Git. Unrelated REA defects are handed off in `/tmp/rea-analysis-efficiency-bugs-20261012.md`, not fixed in this round. Other domains remain incremental, not claimed complete. ### SQLite round result: existing controls suffice No production/API, default, provider annotation, SDK or cache change is justified. The current shipped tool already preserves full selected-table schema while `columns: ["fid", "NAME", "ISO_A3"]` avoids unrelated geometry values. QGIS SDK replies fall from 485,277 to 18,509 bytes (about 96.2%). Both paired selected-fact comparisons pass; full SQL/schema/null/tagged sample facts and database/WAL/engine identity remain intact. SDK time and CPU do not improve: selected workflows are slower in these observations, and timings vary substantially. Keep those results rather than crediting bytes as speed. Four corrected actual Codex trials (requested gpt-5.6-terra high, one exact enabled tool, same frozen main runtime) pass every selected fact and cleanup check. Total input falls **57.63% / 36.44%**, uncached **54.14% / 44.08%**. Time is mixed: **4.17% slower / 14.39% faster**; output **10.77% lower / 6.94% higher**. Actual repeated calls stay counted (all=2/2, columns=1/2). This supports scoped existing-selector token savings, not a stable speedup or a new mechanism. The initial four model calls were blocked by the isolated client's approval policy and have no SQLite result; all factual grades fail. The experiment driver now uses its existing exact per-tool approval entry for SQLite while exposing only that selected tool. Corrected cohorts are separate; original failures and costs remain retained. No global Codex configuration or REA authority/annotation is changed. Actual CLI inventory/all/columns results, subjects, caller parameters and IDs equal corresponding complete MCP records; original bytes remain unchanged. Independent read-only SQLite 3.40.1 binding agrees with exact table SQL, eight declared columns and tagged sample. Six existing context/driver tests, Python compilation and JS syntax checks pass. Missing terminal whole-scope counters remain unknown; narrower payload observations verify cleanup and phase events. Existing SQLite documentation and skill guidance already recommend column selection; the measured result does not justify a redundant product change. Other domain lanes remain incremental. ### SQLite round completed — PR #2489 SQLite experiment [#2489](https://github.com/morluto/rea/pull/2489) merged as `45984a4319c8b6dcf2b03e969fbd4330c8432394`. The change is confined to seven experiment files; production implementations, APIs and complete defaults are unchanged. SQLite measurements remain pinned to main `172407787f1842dedbcd27b5385177595f786ce4`. Real CLI/MCP parity and independent read-only SQLite access agree on the requested schema/cells. Subsequent SDK compatibility checks preserve selected facts and source bytes without extending the model-performance scope. The SQLite factual grader distinguishes missing from explicit null and preserves exact JSON scalar types. All four stored model answers pass; omitted `wal` and boolean `row_limit` mutations fail. Original blocked trials, transcripts and usage remain private and intact; review fixes do not rerun models. Decision remains **use existing controls; no new production optimization**. SDK reply bytes fall about 96.2%; actual total model input falls 57.63% / 36.44%, uncached input 54.14% / 44.08%. SDK time/CPU show no improvement and model time remains mixed (4.17% slower / 14.39% faster). These are QGIS/schema-and-sample observations, not universal speed or memory claims. Resource controls remain one CPU, 3 GiB early stop / 4 GiB hard memory and no swap; unavailable final whole-scope counters remain unknown. All four acceptance items for this round are complete. Other packet/signal, SAZ/qlog and application/platform questions remain incremental evidence-led follow-ups; continuations are tracked in separate issues below. No unrelated REA product bug was identified in this round. ## Packet-capture real-data round (2026-10-13) Main is pinned to `3ae826ceba6f25b08bce50bcb51001209bc16b57`, with 23 post-SQLite commits, including bounded PCAP summaries/retained pages, authenticated artifact subjects, unknown-snapshot reuse and shared transcript grading. The new PCAP family already exposes complete defaults plus opt-in summary/pages; do not duplicate it. Existing selected-field TShark inspection remains a separate analyst boundary, not an interchangeable complete-inventory claim. Work is isolated in `perf/2016-packet-real-data-20261013`. First targets are the unmodified HTTP request/response and HTTP redirects recordings published on the official [Wireshark sample-capture page](https://wiki.wireshark.org/SampleCaptures). Pin downloaded sizes/digests and original URLs; do not claim an independently published upstream digest where none is supplied. These are saved captures, not newly acquired traffic or executions of recorded targets. Fix one question: complete capture identity/metadata, all observed and retained inventory counts, source coverage/limitations, and the first two retained HTTP URIs in original order. Compare existing complete inline delivery with summary plus an exact retained URI page on the same frozen runtime. Extra RPC/schema/retry costs remain counted; an exhausted URI page does not prove network completeness. Start with small real captures, where extra paging may be a net loss. Use actual CLI/MCP and independent raw capture facts; actual repeated model tasks determine token/time effects when the comparison remains justified. Negative results are useful and do not justify changing defaults or adding production mechanisms. - [x] Pin runtime/corpora and inspect actual live contracts before measurements. - [x] Compare equivalent selected facts through real complete and summary/page workflows; preserve original replies and independent validation. - [x] Record completed-task token/time/CPU/memory evidence, failed/repeated calls, and justified unverified scope. - [x] Make the evidence-led decision, save useful reproduction/results, and verify any PR before normal merge; no release. Resource controls remain unchanged: serial heavy work, one CPU, 3 GiB early stop / 4 GiB hard memory, no swap and owned scopes. New providers or target execution/mutation are outside this round. Raw captures, replies, model traces and temporary profiles remain private. Unrelated REA defects go to `/tmp/rea-analysis-efficiency-bugs-20261012.md` for team follow-up, not fixes here. ### Small-PCAP result: complete delivery wins on total input Two unchanged official Wireshark recordings are pinned: HTTP `http.cap`, 25,803 bytes / SHA-256 `25a72bdf10339f2c29916920c8b9501d294923108de8f29b19aba7cc001ab60d`; redirects `http_redirects.pcapng`, 47,804 bytes / SHA-256 `ff432a6b71d06cd20720f7763e584014edd0a43c3b55981c682d1b7640207abc`. Local hashes pin downloaded bytes; upstream independently published digests remain unknown. Frozen main runtime file-table SHA-256 is `db050545e94dc305a48042e06df96ac6c64b21ee6c5c4707c787d5e46df79e47`, Linux/Node 24.18.0, SDK 2.3.1, actual Wireshark 4.0.17. Eight real SDK trials (complete/summary/summary/complete per recording) match selected metadata/counts/URI facts, settings and source bytes. Original delivery limitations/IDs/source-versus-page coverage remain retained separately. Complete replies are 7,601 / 7,535 bytes; summary plus a URI page totals 17,540 / 17,240 bytes. All four SDK pairs are slower and consume more payload CPU; memory is mixed. Fewer bytes are not inferred as tokens. Four actual Codex CLI 0.161.0 tasks (requested gpt-5.6-terra high, same question/runtime/providers/two enabled tools) all pass selected facts. Complete input is 38,947 / 38,917; summary/page input 58,779 / 58,584: **total input increases 50.92% / 50.54%**. Output increases 52.95% / 51.48%. Uncached input is mixed, 28.75% lower / 28.74% higher; time is mixed, 103.41% slower / 52.37% faster. Cached input stays included in totals; actual reasoning/output and all calls are retained. No extra/repeated/failed MCP call occurs. Original bytes and all temporary-profile cleanup checks pass. No caching/time cause is inferred. The initial summary grade rejected equivalent explicit labels and a URI object carrying correct page/source coverage; this was an experiment-grader representation issue, not incorrect model facts or a REA defect. The grading boundary now accepts those known forms while rejecting omissions, wrong types, contradictory duplicates, false page exhaustion and unsupported claims. Original reviews/source/answers remain intact; no model is rerun. Nine context/grading regressions and four mutations of a real stored answer pass their intended positive/negative checks. Independent stdlib raw PCAP/PCAPNG/Ethernet/IP/TCP/HTTP-header parsing agrees on 43/271 packets, endpoint counts, URI prefixes and 2/23 distinct HTTP URIs, without invoking Wireshark. DNS associations, protocol-stack dissection and nullable timestamps are not independently validated. Both actual CLI complete results match full MCP result/subject/parameters/ID/limitations; portable CLI summary/page normalized facts and subjects match MCP retained views, preserving distinct caller/source forms. **Decision: no production optimization.** Keep complete defaults and existing explicit choices. These compact captures and this question do not justify a new API, automatic summary switch, plugin layer or cache. Larger captures, other protocols/platforms and model workloads remain incremental/unverified. Heavy work remains serial under one CPU, 3 GiB early stop / 4 GiB hard memory and no swap. Build peak is 2,575,732,736 bytes; payload cleanup/zero phase limit events are verified. Missing terminal whole-scope counters remain unknown and strict resource grades false. Raw captures/results/traces/config remain private. No unrelated product defect is identified or fixed; no release is performed. ### PCAP experiment acceptance and completed decision [PR #2640](https://github.com/morluto/rea/pull/2640), commit `c7105d9723c835b5e0122f5fc6cfbea86265c349`, preserves the negative compact-PCAP result. [Curated corpus, source/runtime pins, measurements and reproduction](https://github.com/morluto/rea/blob/c7105d9723c835b5e0122f5fc6cfbea86265c349/experiments/analysis-efficiency/pcap-small-captures.md). Final scope is nine experiment files and one discovered evaluation test; production APIs/defaults/cache are unchanged. SDK acceptance authenticates complete/summary/page Evidence through the pinned runtime's existing parser. It preserves subject/path/digest, exact requested facet/range/coverage and JSON scalar values, producer/tool/operation ownership, unique reply IDs and linked retained-parent ID/digest. Present normalized limitations/unknowns must be string arrays; absence and valid empty arrays remain distinct. Legitimate summary delegation is preserved. Factual and exact-workflow grading are separate. Workflow acceptance requires the planned ordered calls/arguments, successful readable replies and exact citation cardinality. Failed or malformed replies retain diagnostics and supported partial facts. Synthetic fixtures and consumer fault injections establish acceptance guards, not real-provider malformed behavior. All 18 original SDK/model receipts authenticate. Thirty-four context/grading regressions, six discovered comparator scenarios and all four stored model answers pass their recorded checks without model reruns. The comparator uses the existing evaluation project; the duplicate manual suite is removed. Original bytes/tokens/timers and runtime `3ae826ceba6f25b08bce50bcb51001209bc16b57` remain unchanged. **Decision:** for these two compact HTTP captures and the fixed metadata/URI question, summary/page total input worsens about 51% in both pairs; keep existing complete defaults. Other question/domain results are not inferred from this corpus. Future bounded comparisons may use existing protocol/field discovery to select exact fields on real non-HTTP captures, counting discovery/schema/RPC/retry costs and preserving provider-specific field identity. Larger captures, signal, SAZ/qlog and application questions remain unmeasured lanes. Plugin SDK and cross-session engine caching remain deferred. Further opportunities are tracked in the separate issues listed below.

Initial implementation source pins on feat/compatibility-first-analysis-20261012:

• 16338af50: public SDK/Transport cost measurements, pinned real-artifact provenance and an owned, resource-bounded experimental runner.
• dc8a19cec: precise current inspection output types and retained/portable inventory summaries and pages, preserving the complete default producer output and historical nested Evidence parsing.

The inventory checkpoint passed 47 related CLI/MCP/domain/service tests. The public boundary scenario retains every occurrence in a 520-member ZIP, removes the original archive, selects and pages original records, distinguishes a partial source from a proven absence, accepts authenticated historical nested Evidence without inserting new defaults, and verifies export → close → missing retained reference → import → equivalent view. Advertised SDK-converted schemas are validated with the declared JSON Schema dialect. Existing comparison completeness tests also passed.

The frozen control runtime is 42b0ed126df7d5b908ac369715378d5e519051b7, not moving main. Preliminary real-artifact calls have exercised Obsidian, NewPipe, ShareX, OpenWrt, SQLite WASM and jq/Ghidra. The corrected experimental SDK options allow jq's real Ghidra run to finish; the initial driver's 60 s timeout is explicitly excluded from REA regression claims. SQLite's current producer completes, but the complete inline reply exceeds the transport frame; an explicit retained-Evidence export recovery is being measured separately. No global speedup is claimed from these preliminary runs.

All heavy work runs serially in unique owned Linux cgroups with one CPU, a 4 GiB hard ceiling, no swap, 192 tasks and an earlier 3 GiB stop threshold. Host available memory is checked before and during work. The reported runs have no observed OOM or task-limit events. The next increment will compare the same analyst facts through optional summary delivery before deciding whether to retain that optimization; analyzer presets and the static domain descriptor pilot follow afterward.

Implementation checkpoint: compatibility, analyzer tradeoffs and static WASM pilot

Implementation sources: feat/compatibility-first-analysis-20261012.

1. Typed inventory and opt-in retained views

• inspect_artifact now advertises the known nested inventory output with exact types. Historical complete Evidence input parsing remains separate, so schema defaults cannot rewrite authenticated older records.
• The existing complete delivery stays the default. Explicit detail: "summary" retains the original inspection and atomic inventory Evidence, returns a derived summary with its own identity, and supports exact-path inventory pages through inspect_analysis_view.
• Partial inventory coverage, unexplored branches, integrity contradictions, original logical paths, caller omission and empty selections are preserved. Page exhaustion is not a claim of absence when the source is partial.
• Two alternating Obsidian pairs preserve the selected facts and atomic source ID. Compact tool-result JSON is 937,404 bytes for complete delivery versus 16,322 for summary plus focused paths, including lifecycle calls: approximately 98.3% less. Catalog JSON increases by approximately 1.9%. The two elapsed observations do not establish a statistical speedup or reduced upstream analysis work.

Recorded results: Obsidian pairs.

2. Real task-scoped Ghidra analyzer experiment

The existing opt-in analyzer control was tested against unchanged defaults using real jq 1.8.2, Ghidra 12.1.4, a fresh ephemeral database, one CPU, and the same entry/main question. Both oversized completed main dossiers were recovered through existing retained native views; transport errors remain recorded.

One disabled/default pair took 174.77/276.23 seconds. Main pseudocode, referenced strings and block count agreed. However, callee 0x40daa0 had 604 recovered body bytes in eight ranges by default, versus 164 bytes in four ranges after disabling Decompiler Switch Analysis, despite the same 646-byte span. This is a concrete quality counterexample to a general safe-fast preset. Production defaults remain unchanged; no new general preset is introduced. A separate real coreutils/Ghidra probe rejects an unknown analyzer before bridge readiness and successfully closes the session.

Recorded results: jq analyzer pair.

3. Small static WASM ownership pilot

• One statically composed WASM module owns the named contract, CLI command, construction and cleanup binding. CLI/MCP share it; existing public factories, tool names, arguments and complete output remain compatible. Catalog position does not select the handler/schema.
• The existing service still owns resources whose cleanup failed and permits retry. No external loader, generic plugin SDK, dynamic discovery or engine database cache was introduced.
• Retained WASM summary and section/import/export/candidate/glue/text/tool-profile views project already completed Evidence without repeating WABT. Exact WAT forms, UTF-16 text boundaries, original provenance, explicit execution/network states and unknowns are retained.
• WAT SHA consistency is checked at the owning model boundary for producer and portable view inputs.

Production commit: 0002caa07.

Real application compatibility checks

Six baseline/pilot pairs use frozen runtimes and identical selected provider settings through public MCP SDK calls: Obsidian ASAR, NewPipe APK, ShareX DLL, OpenWrt firmware, SQLite WASM and historical published WETH bytecode. All selected facts agree under the disclosed rules. Original target bytes remain unchanged in every run. Binwalk generates per-run region UUIDs: both original sets are retained in the report, and physical-region equality excludes only those lookup values. SQLite's 15,382,128-code-unit WAT exceeds the frame in both revisions: the control exports complete Evidence, while the pilot reads its summary and first four exports inline. Inline totals exclude exported file bytes and are not presented as a size reduction comparison.

WETH provenance is the official published historical JSON-RPC example, not a verified live-chain response; live retrieval returned HTTP 403. These are Linux x64 observations, with no real IDA/Hopper/macOS/Windows/Harmony claims.

Recorded results and qualifications: real artifact pairs.

Actual model behavior and work in progress

Real Codex CLI 0.161.0 trials use the requested gpt-5.6-terra alias with high reasoning, a private temporary profile, and this branch's frozen MCP runtime. The resolved server-side model identity is not inferred. The initial Obsidian trials were factually correct, but exact-tool filtering alone did not establish an efficiency win.

A real SQLite model trial recovered all 12 requested facts correctly but made 42 tool calls after confusing summary kind with WASM facet and reading unnecessary WAT pages. The tool description now supplies the exact view: {kind: "summary"} shape and the fields it returns, without adding aliases or changing schemas/defaults. The same task is being repeated, followed by actual model tasks across Android, managed, firmware, EVM, selected JavaScript, inventory, browser and native analysis. A real public Excalidraw capture already confirms a loaded drawing UI, complete requested DOM/accessibility/URL capture and termination of the owned headless browser; model review remains pending.

All heavy work runs serially in owned transient scopes: one CPU, 4 GiB hard memory cap, 3 GiB sampled early stop, no swap, and 192 tasks. This study's recorded scopes report zero observed OOM/task-limit events. Source checks, build and generated-document checks pass. Full original replies/transcripts/binaries/credentials remain outside Git. Factual review and resource/cleanup checks are required independently of model exit status.

Saved implementation and verification checkpoint — 2026-10-12

The three bounded increments are implemented or experimentally resolved on feat/compatibility-first-analysis-20261012. Recorded verification source pins include:

• 860f1ffe3: cross-domain real-model grading, qualified selected-JavaScript comparison, and original resource-capacity failures.
• 7398bb818: genuine old Evidence migration, nonempty managed imports, and final verification receipts.

The experiment guide and interpretation link reproducible drivers and curated results. Downloads, complete exported Evidence, frozen runtimes, raw transcripts, and disposable authentication/configuration remain outside Git. No PR has been opened.

Decisions supported by the measurements

Increment	Result and decision
Cost measurement / nested inventory / retained views	Precise known nested output and caller-selected inventory/WASM views preserve original complete Evidence. Obsidian complete result delivery is 937,404 compact JSON bytes; summary plus exact path views is 16,322 bytes, about 98.3% less, including all lifecycle/view calls. Two alternating pairs preserve the requested facts and atomic source identity. This saves delivery work; it does not establish reduced upstream engine analysis.
Optional Ghidra analysis settings	One jq disabled/default pair takes 174.77/276.23 seconds. Main pseudocode, strings, and blocks agree, but a callee loses recovered body bytes/ranges: 604 bytes in eight ranges becomes 164 bytes in four. Keep the production default; the experiment does not justify a generally safe fast preset.
Small descriptor	WASM uses a statically composed named contract, service factory, existing CLI/MCP registration, and owned cleanup. Existing tool/command names, provider choices, complete defaults, legacy service injection, and record lifecycle remain. No external plugin loader/SDK or cross-session engine-database cache is introduced.

Precise schemas have a cost: the complete catalog is 2,387,588 compact JSON bytes at the final measured runtime versus 2,326,609 in the baseline (about 2.6% larger). No global discovery or startup improvement is claimed.

Actual migration, beyond synthetic old-input fixtures

The migration receipt uses genuine public baseline outputs from 42b0ed126df7d5b908ac369715378d5e519051b7:

1. Import the old complete SQLite WASM Evidence bundle into frozen runtime 259e99dd906290189217cf0fb1a19769bcf87101.
2. Read the new summary and first four export forms through retained views.
3. Export again and assert the entire original WASM record is deeply equal, with the same authenticated Evidence ID.
4. Pass the old complete Obsidian inspection inline to the new summary view; preserve its parent ID, atomic inventory ID, and manifest.
5. Verify both old input files remain byte-identical.

WABT is explicitly unavailable and no producer operation is requested. This confirms portable-result reuse through existing import/export, without another provider run. The five-call workflow completes in 5.458 seconds, sampled aggregate peak 700,542,976 bytes, with no observed OOM or task-limit events.

The default complete SQLite CLI also returns the same source Evidence ID, complete normalized result, and raw result as the authenticated baseline MCP export (16,439,561 output bytes). The original oversized complete MCP response remains a reported transport error in both revisions; it is never relabeled as successful inline delivery.

Broader shipped-artifact and real-model evidence

The earlier six real artifact pairs are supplemented by:

• Selected Obsidian JavaScript: the same two source files, all 24 observed main.js module identities, statistics, Electron observations, fixed limits, family coverage, and explicit unknown counts agree. Two heap-dependent parent byte budgets are preserved with both original values/paths and qualified separately. Source Evidence is never rewritten. Coverage remains partial: 36 unselected relevant files and 384 semantic unknowns.
• ShareX HelpersLib 19.0.2: a genuine shipped DLL with 11 ModuleRefs, 147 PInvoke declarations, and 225 native implementations. Complete normalized artifact/boundary results and source Evidence IDs agree between baseline and pilot. An additional real model task preserves all 11 references, the first three complete PInvoke records, summary flags/counts, MVID, coverage, and source reference in one call. The assembly is not executed; native dependency behavior is unverified.

Ten follow-up Codex CLI reviews, plus the separate nonempty-managed task above, cover native, managed, Android, firmware, Electron/JavaScript, WASM, EVM, and browser questions. They use disposable local configuration pointing at the modified REA MCP, requested alias gpt-5.6-terra with high reasoning, and exact per-task tool allowlists. A requested alias is not presented as a verified server-side model identity.

The same-question SQLite model pair preserves all 12 requested facts. After the already-committed exact summary guidance, calls change from 42 to 3 and reported input tokens from 304,698 to 74,387; unnecessary WAT pages disappear. Question/instruction/provider/allowlist fingerprints match. This is one stochastic pair, not a statistical or general causal result, and token totals are not a currency-cost estimate.

Important incomplete outcomes remain visible:

• The JavaScript model keeps core facts and all selected module identities but omits full budget/family coverage provenance; strict full-answer review fails.
• Real Excalidraw capture returns complete DOM/accessibility/URL Evidence and terminates the owned Chromium process. Model answers report two accessibility metadata fields unknown after client context clipping; strict selected-field review fails.
• Requested under-development Codex code-mode flags still result in a direct MCP call in the actual trace, with no JavaScript executor. No bridge/composition improvement is credited.
• Firmware region UUIDs and inventory IDs selected under a different integrity policy retain their original meanings. Comparison qualifications do not normalize producer output or erase source choices.
• WETH is a published historical bytecode example; live RPC returned HTTP 403. Deployment authenticity remains unknown.

Verification and resource limits

Verification receipts record:

• 42 actual WABT 1.0.42 CLI/MCP cases passed, including real output/schema/Evidence checks.
• The final seven-file contract/composition run passed 51/52 tests and hit an existing 20-second child deadline under the one-CPU lane. The same unmodified presentation test passed alone in 10.835 seconds. Both outcomes remain recorded; the combined gate is not claimed to have passed.
• Heavy work ran serially in owned scopes: one CPU, 4 GiB hard memory, 3 GiB early stop, no swap. This checkpoint's recorded scopes have zero OOM/OOM-kill events. One original Codex+Chromium trial hit the 192-task ceiling below 1 GiB memory and was aborted/cleaned up; the explicit 256-task browser retries preserve the memory/CPU limits and have no observed limit events.

No full check:pr, package-install verification, IDA/Hopper, Windows/macOS, Harmony, ADB-device, or other unavailable-provider success is implied. Unchecked acceptance items retain those stronger boundaries for later review. The issue remains open; no merge/release is requested.

At the user's request, newly discovered probable REA defects are recorded in a separate local /tmp team-handoff document and are not repaired during this follow-up. The latest two commits contain research drivers, curated measurements, and experiment documentation only. The original checkout is preserved.

The [same-question SQLite model pair](https://github.com/morluto/rea/blob/7398bb818c64f1586240b2dd5ed0c8bfd1826807/experiments/analysis-efficiency/results/model-wasm-20261012.json) preserves all 12 requested facts. After the already-committed exact summary guidance, calls change from 42 to 3 and reported input tokens from 304,698 to 74,387; unnecessary WAT pages disappear. Question/instruction/provider/allowlist fingerprints match. This is one stochastic pair, not a statistical or general causal result, and token totals are not a currency-cost estimate. Important incomplete outcomes remain visible: - The JavaScript model keeps core facts and all selected module identities but omits full budget/family coverage provenance; strict full-answer review fails. - Real Excalidraw capture returns complete DOM/accessibility/URL Evidence and terminates the owned Chromium process. Model answers report two accessibility metadata fields unknown after client context clipping; strict selected-field review fails. - Requested under-development Codex code-mode flags still result in a direct MCP call in the actual trace, with no JavaScript executor. No bridge/composition improvement is credited. - Firmware region UUIDs and inventory IDs selected under a different integrity policy retain their original meanings. Comparison qualifications do not normalize producer output or erase source choices. - WETH is a published historical bytecode example; live RPC returned HTTP 403. Deployment authenticity remains unknown. ### Verification and resource limits [Verification receipts](https://github.com/morluto/rea/blob/7398bb818c64f1586240b2dd5ed0c8bfd1826807/experiments/analysis-efficiency/results/verification-20261012.json) record: - **42 actual WABT 1.0.42 CLI/MCP cases passed**, including real output/schema/Evidence checks. - The final seven-file contract/composition run passed 51/52 tests and hit an existing 20-second child deadline under the one-CPU lane. The same unmodified presentation test passed alone in 10.835 seconds. Both outcomes remain recorded; the combined gate is not claimed to have passed. - Heavy work ran serially in owned scopes: one CPU, 4 GiB hard memory, 3 GiB early stop, no swap. This checkpoint's recorded scopes have zero OOM/OOM-kill events. One original Codex+Chromium trial hit the 192-task ceiling below 1 GiB memory and was aborted/cleaned up; the explicit 256-task browser retries preserve the memory/CPU limits and have no observed limit events. No full check:pr, package-install verification, IDA/Hopper, Windows/macOS, Harmony, ADB-device, or other unavailable-provider success is implied. Unchecked acceptance items retain those stronger boundaries for later review. The issue remains open; no merge/release is requested. At the user's request, newly discovered probable REA defects are recorded in a separate local `/tmp` team-handoff document and are **not repaired during this follow-up**. The latest two commits contain research drivers, curated measurements, and experiment documentation only. The original checkout is preserved.

Added the clarified optimization priorities and gradual migration policy to the issue body under Optimization priorities and progressive migration.

• Primary: actual agent token consumption and time to a correct answer for the same question. Count discovery context, cached/uncached input, output, retries and follow-up calls; keep compact JSON bytes separate from actual tokens.
• Also optimize/control: aggregate memory and CPU usage, including retained Evidence and representation expansion, with host resource safeguards.
• Acceptance conditions: useful facts, provenance/coverage, caller choices and existing-user compatibility. Domain verification grows progressively; native PE, DOS and deeper runtime/firmware tasks need not all be completed in one pass.

Existing clients against the candidate retain old tool/command names, existing request behavior, complete defaults, provider choices and session semantics in the verified scope. New summary/views require explicit selection. Genuine old Evidence migration preserves authenticated records and IDs. New-capability requests against older servers require actual schema discovery and supported equivalents; no universal automatic fallback is claimed. The complete catalog intentionally has additive/more precise schemas and grows about 2.6% in compact JSON, so the catalog is not byte-identical.

The work remains on the isolated branch, without merge/release or a forced user migration. Compatibility evidence covers the recorded baseline/workflows; further historical versions, clients and platforms are verified progressively.

Inventory/WASM compatibility evidence — #2122

Implemented in #2122. Integrated runtime pin: c22111eca2c4bc84a084f12711f405b3e7422a40.

Separate post-integration receipt:

• npm run verify:wasm:package passes 42 real WABT CLI/MCP cases after actual private-prefix package installation.
• Genuine old SQLite/Obsidian Evidence import/view/export passes again with WABT unavailable. Original records, IDs and bytes are preserved.
• A fresh public SDK cohort preserves old complete Obsidian delivery (937,404 compact JSON bytes) and all selected source facts/identities. Explicit summary plus exact paths remains 16,322 bytes. Integrated catalog JSON is 2,359,082 bytes, about 1.4% above the original frozen baseline; this includes intervening main changes and does not isolate the PR's contribution.
• Integration scopes record no OOM/OOM-kill or hard-limit abort. The complete source-check scope records three memory.high events; those remain visible. Earlier model/capacity failures and partial answers remain qualified, with their original runtime fingerprints.

The transition preserves the existing complete path and adds explicit focused delivery. Existing requests do not silently change output or analysis defaults. This makes the implemented scope suitable for review; it is not a universal compatibility guarantee or a claim that all advertised domains have completed verification. Native PE/DOS, other host/providers and deeper tasks remain progressive work.

Complete managed producer tables stay in the private lab outputs; the PR keeps curated identities, selected records, counts, coverage and full-payload digests. New out-of-scope REA findings stay in the separate local team-handoff document for later repair.

First-call WASM delivery and measurement validity

The inventory/WASM pilot preserves atomic and outer inventory identity, exact WASM source identity, explicit provider controls/search paths and unknown final cgroup counters. Original valid Evidence and complete defaults remain preserved.

Implemented in #2193: optional MCP detail: summary, stripped before provider inputs, retains the complete source and reuses typed summary/export views. Omitted/complete requests and CLI output remain complete. No external plugin SDK, execution authority or cross-session engine cache is added.

Curated pinned methods and observations:

• Public SDK: 3 alternating fresh-process pairs each for SQLite and two digest-verified published VS Code Tree-sitter components (18 runs / 9 comparisons). Selected validation/count/export/WAT/provider/execution/fetch facts and the complete original source Evidence IDs match in all pairs. Runtime result delivery is 6,433,872 → 18,891 JSON bytes, about 99.7% less. SQLite/CSS already had retained recovery; they remove one call/error and save only about 8% of result bytes. Catalog grows 3,369 bytes (~0.14%).
• Actual Codex CLI: requested gpt-5.6-terra high, CLI 0.161.0, fixed question/configuration, four allowlisted REA tools and isolated profiles. Three SQLite pairs plus one pair per VS Code component (10 trials) preserve all 12 requested producer facts, observed Evidence IDs, target bytes and profile cleanup. All five candidates select first-call summary.
• Token/time observations: SQLite median total input 96,832 → 79,264 (~18% less) and answer time 61.521 → 55.656 s (~10% less), while uncached input rises ~7%. VS Code single pairs reduce total input ~49%/~68% but answer time increases ~84%/~22%. Cached/uncached input/output, failed calls and extra discovery are retained separately. This supports optional smaller delivery; it does not prove uniform speedup, currency saving or a broad causal effect.
• Resource qualification: one CPU, 4 GiB hard/3 GiB early-stop, no swap and bounded tasks remain active. Model last-sampled peaks are 656–944 MiB with no observed limit events. Earlier cohort receipts lack verified final counters. The corrected grader rechecks all ten existing answers without rerunning them: facts/IDs/cleanup still match, final resource conditions are unverified. No absent-late-event or fully resource-qualified performance claim is made.
• Failed attempt retained: the initial 18-run SDK cohort did not activate the option because enum probing missed SDK-generated $ref. Its source/replies remain separately archived and are excluded from benefit claims. The corrected driver validates the actual advertised 2020-12 request schema.

Further work remains question-specific: native PE/DOS workflows, descriptor lifecycle/capacity evidence, and cost breakdowns with the same useful facts. Reduced Ghidra analysis previously lost callee facts and remains unpromoted. Dynamic plugin SDK and cross-session engine caching stay deferred.

Native PE exploration: scope and limits

The next real native PE component is the existing digest-verified ShareX 19.0.2 ShareX.exe (198,656 bytes, SHA-256 46af1ccc514b395cb703633abb5a505a771942b7db9b1915f31aeea541b3685f).

Actual Linux Ghidra 12.1.4 loads it as x86:LE:64:default, compiler windows, image base 0x140000000, entry 0x1400125c0, nine mappings; original/modified source digests agree and the session closes successfully.

The public inspect_native_load_image result explicitly reports unsupported independent verification for PE (it currently supports DOS MZ, explicit DOS COM and raw-binary targets), while retaining its actual observations. This is an advertised capability boundary, not a newly established REA bug or a complete native-PE/model pass. The 190-second exploratory scope peaks at about 1,011 MiB sampled family memory, with no sampled abort/limit event; final counters remain unverified. No target code or GUI is executed. Deeper PE semantics/model work and real DOS inputs remain progressive tasks.

Native experiment #2216 is based on main 10400fdb57e4226c5ce15af17968a664f35498ce after #2122/#2193 merged. Curated methods, artifacts, measurements and limitations.

This checkpoint adds experimental inputs/drivers/grading and documentation; it changes no production CLI/MCP contract, default, provider or Evidence lifecycle.

• Real Ghidra 12.1.4 on Linux inspected the shipped native ShareX 19.0.2 PE component and original UPX-compressed FreeDOS EDLIN 2.24 DOS MZ. Requested retained facets match original producer facts, target digest, parent ID and distinct derived IDs. DOS static load-image verification passed. Windows runtime, unpacked editor logic and DOS COM remain unverified.
• Delivery has a useful counterexample: the 18-byte PE entry dossier is 50,936 JSON bytes, while four selected replies total 68,257. DOS is 224,670 versus 70,539. These are bytes for already-retained reads, not token or first-call savings: the initial complete dossier still runs and is delivered. This argues for question-specific selection rather than blindly generalizing WASM's first-call option.
• Three real Codex CLI gpt-5.6-terra high trials (PE twice, DOS once) matched selected source facts/references and completed session/profile cleanup with original target bytes unchanged. Input/cached/uncached tokens were PE1 451,337/399,616/51,721; DOS 730,578/658,944/71,634; PE2 498,322/429,056/69,266. Times were 130.073/134.435/192.373 seconds. There is no measured overall native speedup. An explicit seven-tool subset was used, so this is not full-catalog discovery verification.
• The advertised native summary recipe is actually rejected. The SDK reproduced it on both inputs; the PE agents incurred two/one failed calls and recovery work. Recorded in the requested /tmp bug handoff for team repair, not fixed here. The first SDK harness mistake and original grading shape failures remain preserved alongside corrected exact-value regrades.
• SDK/model sampled peaks remained about 0.94–1.32 GiB under the aggregate bounds, with no abort and zero last-observed limit counters. Final closeout counters are unavailable; strict resource-qualified grades remain unverified.

The next useful optimization comparison is existing native primitives versus a full dossier for the identical question, followed by larger/unpacked native inputs. Keep defaults unchanged and leave the summary-description bug for its own team fix. No version publication or deployment performed; #2016 stays open.

Native results and EVM experiment rationale

Native experiment merged in #2216, commit 1770f38cfc6cbe87491d0de8b8730c305c5cf8ea.

The production API/defaults remain unchanged. Experimental facts are separate from original Evidence references; stale DOS load-image identity and cross-producer/view collisions are rejected. A DOS load-image model grade now requires its actual completed, referenced observation. Raw answers, first grading failures, regrades and measured costs remain outside Git. Curated measurements retain the PE size regression and unknown final resource counters. Fewer retained-view bytes are not treated as a first-task token or latency win.

The EVM pilot shares the existing exact operation/CLI name and typed lifetime through a small static descriptor, preserves legacy service injection/defaults, and compares the actual SDK-converted catalog. Wiring alone is not a performance claim.

Preparation against an earlier frozen main control (b1bf4a70d44191348ca20a91a52fb663da4daed0) includes two actual WETH MCP measurements with exact fact agreement, and 59 passing real EVM CLI/MCP verifier cases using unchanged EVMole 0.9.3 and privately installed solc 0.8.30/strace. The latter took 233.1 s with sampled family peak 1,192,730,624 bytes; final cgroup counters remain unknown. Public Uniswap v3-core 1.0.1 Factory/Pool compiler runtime templates were acquired from the official npm package with verified archive integrity, exact member/carrier/decoded digests, original template bytes and explicit unknown immutable-reference metadata. Actual control CLI observations infer 7/26 functions, respectively; equal published ABI counts alone are not selector-set or deployed-instance verification. Fresh latest-main controls and candidate checks will follow before recommendations.

Priorities remain actual model tokens and time to a correct answer, then aggregate CPU/memory. Heavy work remains serial under one CPU and a 4 GiB hard/3 GiB early-stop memory scope.

<!-- gh-comment-id:6127989487 --> @N0zoM1z0 commented on GitHub (Oct 12, 2026): ## Native results and EVM experiment rationale Native experiment merged in [#2216](https://github.com/morluto/rea/pull/2216), commit `1770f38cfc6cbe87491d0de8b8730c305c5cf8ea`. The production API/defaults remain unchanged. Experimental facts are separate from original Evidence references; stale DOS load-image identity and cross-producer/view collisions are rejected. A DOS load-image model grade now requires its actual completed, referenced observation. Raw answers, first grading failures, regrades and measured costs remain outside Git. [Curated measurements](https://github.com/morluto/rea/blob/1770f38cfc6cbe87491d0de8b8730c305c5cf8ea/experiments/analysis-efficiency/native-entry-views.md) retain the PE size regression and unknown final resource counters. Fewer retained-view bytes are not treated as a first-task token or latency win. The EVM pilot shares the existing exact operation/CLI name and typed lifetime through a small static descriptor, preserves legacy service injection/defaults, and compares the actual SDK-converted catalog. Wiring alone is not a performance claim. Preparation against an earlier frozen main control (`b1bf4a70d44191348ca20a91a52fb663da4daed0`) includes two actual WETH MCP measurements with exact fact agreement, and 59 passing real EVM CLI/MCP verifier cases using unchanged EVMole 0.9.3 and privately installed solc 0.8.30/strace. The latter took 233.1 s with sampled family peak 1,192,730,624 bytes; final cgroup counters remain unknown. Public Uniswap v3-core 1.0.1 Factory/Pool compiler runtime templates were acquired from the official npm package with verified archive integrity, exact member/carrier/decoded digests, original template bytes and explicit unknown immutable-reference metadata. Actual control CLI observations infer 7/26 functions, respectively; equal published ABI counts alone are not selector-set or deployed-instance verification. Fresh latest-main controls and candidate checks will follow before recommendations. Priorities remain actual model tokens and time to a correct answer, then aggregate CPU/memory. Heavy work remains serial under one CPU and a 4 GiB hard/3 GiB early-stop memory scope. No broad native, Windows runtime, DOS COM, live-chain or resource-qualified speedup claim is added; unrelated REA bugs remain in the requested `/tmp` handoff for the team. The remaining #2016 acceptance work stays open.

EVM static descriptor: real verification

Implemented in #2261.

The descriptor has only the existing exact named contract, CLI name and legacy factory. The host preserves the injected full service and passes its selected cleanup owner to registration, removing the redundant fallback. No engine protocol, default/full result, provider setting, pack selection or general plugin SDK changes. Curated evidence and reproduction pins control/candidate/runtime/driver digests and retains qualifications.

Verification now includes:

• Six before/after EVM SDK pairs across WETH and public Uniswap v3-core Factory/Pool templates. Facts/settings match; the complete SDK catalog is byte-identical, SHA-256 8664e42fd5225645cfd910f440f731c67ac198d3d53aa85b5c485374c74cf603. Full reply bytes remain unchanged. Actual candidate selector multisets match the independently derived published ABI; deployed/immutable authenticity stays unknown.
• All 59 real EVM CLI/MCP verifier cases pass against the modified runtime, with unchanged EVMole 0.9.3 and private solc/strace prerequisites. Selected syscall scenarios report no target execution/network sockets and no remaining owned descendants.
• Post-descriptor actual public MCP regressions pass for SQLite WASM, ShareX managed metadata, Obsidian inventory, NewPipe APK, OpenWrt firmware and jq native/Ghidra. Original identities/bytes and named schemas are verified. These selected Linux scopes do not establish unavailable OS/provider/device or browser/AST coverage.
• Six actual Codex CLI trials request gpt-5.6-terra high, with temporary isolated configuration pointing at modified REA MCP: each artifact twice, one successful call each, no failed calls. Every selected fact/reference/integrity/profile-cleanup check passes. Full Uniswap tasks consume 36,416–36,974 uncached input tokens; WETH consumes 25,318–25,516. Requested alias is not a resolved-model identity claim; the one-tool subset is not full-catalog discovery evaluation.
• Five SDK boundary scenarios cover named schemas, duplicate registration, malformed/unavailable/incompatible-output failures, healthy peers, cleanup retry and cancellation settlement/recovery through recording ports. Separate service/provider/WASM boundary checks pass. Recording ports are not real-provider claims.

This establishes smooth internal wiring, not a new token reduction from the descriptor. Second-pair latency/CPU are similar; slower first controls and differing verifier durations are not attributed to unchanged algorithms. All heavy work remains serial in one-CPU, 4 GiB hard/3 GiB early-stop, no-swap scopes. Final transient-cgroup counters remain unknown, so strict overall resource-qualified model grades remain unverified. Raw receipts/transcripts/artifacts stay outside Git; no universal speedup or OOM-absence claim is made.

Next measurement question: explicit precise EVM interface delivery for the same requested facts, retaining the complete bytecode/Evidence and old defaults.

Explicit EVM summary delivery

Implemented in #2308: opt-in MCP detail: summary and typed retained/portable EVM views. Complete defaults, provider inputs, CLI and original full Evidence remain unchanged. All inferred candidate facts and explicit unknowns are returned; unsupported retention is rejected before analysis. Derived IDs link to original parents, and function rows/hex/stdout/stderr remain recoverable without producer reruns.

The first real Factory comparison preserves identical requested facts and reduces one MCP reply from 110,424 to 14,442 bytes (~87%), while the complete catalog grows by 7,709 bytes. Wall times are 3.711/3.881 s; this does not establish a speedup or a token reduction. A corrected separate four-call retained-source verification passes; old two-field complete calls remain usable and actual old-server schema discovery falls back to complete without unsupported arguments. The first retained probe failed only the experiment consumer’s public bundle-envelope assumption; original production replies remain archived.

Repeated WETH/Factory/Pool SDK and actual Codex comparisons, old-Evidence continuation and whole-task token/time accounting are required before a recommendation. Missing terminal resource counters remain unknown.

EVM retained-interface delivery: measurements and compatibility

Implemented in #2308.

Behavior and migration: opt-in MCP inspect_evm_interface detail: "summary" returns every producer-inferred candidate, both identities, original limitations and explicit unknowns without hex/duplicate stdout. Original complete Evidence and its parameters/raw result/ID remain retained. Derived views have their own IDs and parent links. Omitted/complete requests and the existing CLI keep their full behavior. Actual new default replies pass the frozen old advertised schemas. Three authentic old bundles pass import, retained/inline reads and export with original records, IDs and source bytes unchanged; a reproducible public SDK/CLI verifier runs with the analysis limiter explicitly unavailable. Fresh Factory retained and original Pool migration workflows also pass.

Measured results: six repeated SDK fact/settings pairs pass across WETH and official Uniswap Factory/Pool compiler templates. Result JSON is respectively 42.53%, 86.92% and 82.05% smaller. The pinned complete catalog grows by 7,709 bytes, retaining 184 tool names/order; only EVM/generic-view definitions change. These byte measurements are not token estimates.

Twelve actual Codex CLI trials, requested gpt-5.6-terra high, use the same questions/inputs and one enabled EVM tool. Five of six candidate calls choose summary, one chooses complete. Uncached input improves in only two pairs and task time improves in only two. Aggregate uncached input is 163,584 → 146,570, while output is 8,953 → 10,397 and elapsed time is 300.954 → 319.263 seconds. Every core field and reported Evidence ID matches producer observations, but only three answers pass the existing verbatim ordered limitation-list check. Four failures preserve all source strings with extra statements/reordering; five paraphrase or omit source caveats. All strict reports and trials remain intact. No stable token/time win or twelve fully qualified successes are claimed.

Verification: 64 focused checks on the feature pass. All 59 existing real EVM CLI/MCP verifier cases pass with solc 0.8.30 and syscall tracing. Six actual shared-domain regressions pass: SQLite WASM, ShareX managed metadata, Obsidian inventory, NewPipe/JADX, OpenWrt region and jq/Ghidra entry analysis. This does not extend whole-app AST/browser/firmware or new Windows real-provider claims.

Heavy work remains serial: one CPU, 4 GiB hard/3 GiB early-stop, no swap and bounded tasks. Final counters for completed scopes remain unverified; sampled values are not substituted. Failed receipts and raw JSON/transcripts/binaries/toolchains stay outside Git.

Curated measurements, exact pins, failure/qualification details and reproduction.

Complete defaults remain unchanged. General plugin SDK and cross-session analysis caches remain deferred.

EVM delivery outcome and preset-lifecycle scope

Implemented in #2308, commit f76163c2467db623f9de0bda757c9d8610ca9565.

The merged increment adds selected EVM delivery while keeping existing complete defaults and source Evidence usable. Its curated report preserves the repeated byte reductions, mixed real-model token/time outcomes, strict limitation failures and resource qualification gaps. It does not force a new analysis default or publish a release.

Next scope: close the remaining task-scoped preset lifecycle proof gaps through actual public CLI/MCP workflows—visible profile differences, cancellation/failure/cleanup and exact target/profile snapshot compatibility. The prior disabled-switch jq result changed a callee body, so the production default remains unchanged and no general fast-preset recommendation is introduced. Snapshot JSON verification is distinct from the deferred cross-session engine database cache. Remaining #2016 acceptance items stay open, and unrelated REA defects continue to be recorded privately for team repair.

Real preset lifecycle verification — #2349

Experiment runtime baseline: main f76163c2467db623f9de0bda757c9d8610ca9565. #2349 adds experiment sources and curated documentation only.

Actual Ghidra 12.1.4/JDK 21 public workflows pass on installed GNU true and the pinned public jq entry:

• Exported analyze_function snapshots contain actual query entries, not just equal records from another analysis. Fresh MCP reuse preserves exact task facts/subject/parameters/profile with an explicit cache marker; CLI preserves the original record identity and source snapshot bytes.
• Default/disabled profile mismatch is rejected before headless startup in both directions. Restoring the default accepts its original snapshot. Actual exec traces show one headless launch for each fresh profile and zero for accepted reuse or rejected bindings.
• Both profiles on GNU true pass real pending-JVM startup cancellation, read-only token cleanup, successful fresh work under the same selected target, and native process start-identity verification. Logical run IDs intentionally persist across recovery.
• A real permission fault in the verifier-owned temporary Ghidra project produces cleanup_incomplete/EACCES and retains its resource. After restoring permissions, a second close succeeds with confirmed token cleanup and unchanged target bytes.
• Invalid analyzer requests preserve the exact name in CLI/MCP execution_failure diagnostics; a healthy bundled EVM peer remains usable. Different CLI/MCP error envelopes are handled without losing the source diagnostics.

The selected entry agrees across profiles; the previously observed differing jq callee still prevents a general fast-preset recommendation. Fresh jq function calls take 294.525/298.621 seconds; existing default snapshot calls take 0.222/0.168 seconds, and CLI reuse takes 2.899 seconds. These are verification call sequences, not repeated equivalent whole-question performance cohorts or new architecture gains. Model tokens are not measured in this increment. The existing explicit JSON snapshot mechanism remains distinct from the deferred engine database cache.

The complete jq workflow uses 624.537 seconds, sampled peak 1,218,355,200 bytes and last-observed CPU 567.198 seconds. All heavy jobs remain serial, one CPU, 4 GiB hard memory/3 GiB early-stop, no swap and bounded tasks. Final counters remain unknown; validation peaks/soft-limit events are excluded from efficiency conclusions.

Failed observer assumptions remain archived: primitive-only snapshot equality was not reuse proof; absent activity metadata was not idle proof; logical run identity was not process generation; CLI diagnostics use sibling fields; an unconfigured pwntools ELF peer correctly reported unavailable. These were harness mistakes, not newly demonstrated REA bugs. No production repair, API/default change, installer, model matrix rerun or release occurs.

Curated source pins, scope and reproduction. The remaining acceptance items stay open pending the appropriate scope audit and PR review; this checkpoint does not declare the full #2016 goal complete.

Preset lifecycle evidence delivered

Implemented in #2349, commit 1dd20ce1ff4ab66c74350929577e753aa17a9006.

The merged reproducible verifiers cover actual Ghidra default/disabled profiles, stored snapshot entries and pre-launch profile rejection, SDK startup cancellation, real permission-induced cleanup failure and recovery. Linux shipped GNU true and jq are the recorded scope. Fresh jq analysis takes about 295–299 seconds, while authenticated same-profile snapshot reuse takes 0.17–0.22 seconds through MCP (2.899 seconds via CLI). This verifies the existing replay path; it does not establish a new whole-task/model-token speedup or recommend reduced analysis generally.

Actual socket-cleanup checks pass for both recorded Ghidra profiles. This is lifecycle validation within the recorded Linux/provider scope, not an additional efficiency gain.

Next: finish the EVM descriptor acceptance audit with actual public MCP and unchanged EVMole worker replies, particularly late cancellation and real filesystem cleanup retry. The remaining contract/registration requirement will be assessed against static composition, without introducing the deferred dynamic plugin SDK. Raw observations and resource receipts remain private; unrelated newly observed REA regressions remain in the requested local bug handoff document.

EVM actual worker lifecycle and next cost candidate

#2404 changes experiment verifiers, with production code/API/defaults unchanged.

Actual compiled CLI and stdio MCP workflows pass on pinned WETH and official Uniswap Factory/Pool templates, using unchanged EVMole 0.9.3 plus real prlimit. Each verifies late SDK cancellation after an actual worker reply, real permission-induced cleanup failure/retry, preservation of original malformed-input diagnostics, and a healthy shipped SQLite WASM peer through real WABT. Original files and runtime fingerprints remain unchanged; token sweeps and final point-in-time lineage confirm cleanup.

EVM lifecycle acceptance and managed-metadata rationale

Implemented in #2404, commit ae8051302b5834322fa00cfa31c968ae74ab6ed9.

The actual CLI/MCP lifecycle acceptance item is checked with explicit Linux/provider/late-cancellation scope. Duplicate registration and malformed/incompatible-output SDK tests already exist, but the broader pre-use incompatible-contract requirement remains explicitly open; no general plugin SDK/ABI validator is claimed.

The managed-metadata experiment starts from ae8051302b5834322fa00cfa31c968ae74ab6ed9: freeze the complete workflow, then compare optional overview/retained typed paging with unchanged defaults and provider/Evidence semantics. The same real-model question requests identity, complete classification, frameworks and native boundaries while excluding unrelated custom-attribute/resource inventories, matching the measured 1.27 MB ShareX cost. Repeated real application/model tests and end-to-end costs determine the recommendation.

Managed follow-up checkpoint: PR #2413 adds opt-in artifact summaries and retained/portable metadata pages while preserving complete defaults. Implementation and curated verification pin: 69b4621b5a001879940d12f91f757a958c17f508.

Actual SDK trials use two shipped assemblies from digest-pinned ShareX 19.0.2, with two pairs per assembly. Metadata replies repeat at 1,270,839 → 10,549 bytes and 1,296,839 → 10,937 bytes; all selected facts/settings match. Actual omitted-detail candidate requests reproduce every complete normalized metadata/native-boundary fact and canonical complete Evidence ID from the old runtime. Both old producer records also pass the new SDK portable summary and every collection page, preserving source facts, coverage, row order and lineage. Real SQLite WASM verifies the neighboring shared dispatch path. This is scoped evidence, not a guarantee for every historical release/platform.

The actual Codex findings are mixed and must not be confused with byte savings. Four sequential real CLI trials (requested gpt-5.6-terra high, unchanged question and same two tools, control/candidate/candidate/control) report input tokens 54,821 / 77,594 / 82,426 / 55,296; uncached input 25,637 / 27,162 / 33,018 / 26,112; wall time 63.207 / 46.685 / 67.379 / 62.159 seconds. Both candidate trials select summary and complete the same two calls. Candidate input/uncached input are higher, and latency is mixed. No stable actual token or whole-task speed improvement is claimed. Three answers pass selected fact checks after allowing unambiguous equivalent coverage labels; the second control has strict representation omissions. Full selected grader reports retain unknown final physical resource counters as failures, separately from factual checks.

The original descriptor acceptance item for duplicate/incompatible contracts remains open during its scope audit: SDK duplicate registration and invalid input/provider output are covered, but rejecting a provider reply after execution is not a claim of pre-use contract compatibility. General dynamic plugin/ABI admission remains deferred. Next token optimization must examine actual model-visible discovery/delivery costs rather than infer them from JSON bytes.

Actual model context accounting

Managed delivery implemented in #2413, commit 82cfcee19f18b0eeae9a330ba04e0411cdf85225.

Checkpoint 9ebdcc458c399b9bdecaaca2ef47422888231181 adds opt-in real Codex tool/usage capture; default trials remain ephemeral. Only owned tool calls/replies and numeric usage observations are retained. Account/session metadata, world state, user/developer messages, encrypted reasoning, internal passthrough, auth/config and ambient environment are excluded. Capture failure cannot bypass temporary-profile cleanup. Four focused context-capture tests pass.

A separately identified control diagnostic observes three JavaScript executor calls and four response-usage records despite only two public MCP calls. It first prints broad ALL_TOOLS metadata (client reports a truncated 164,005-token original output), then projects the complete managed result before printing selected identity facts. The retained tool-output values are 41,704 / 2,154 / 13,489 UTF-8 bytes; their sizes are not the exact submitted request context. Aggregate input 76,433 and cached 49,408 agree with the per-response totals. This is a concrete reason not to equate raw MCP reply bytes with model-visible data or call count with model round count; it does not explain every earlier pair or prove a universal mechanism. The earlier direct label describes requested configuration, not verified absence of a client executor.

New identical-question paired captures are running from the committed checkpoint before choosing a narrowly scoped discovery/projection experiment. Existing REA APIs/defaults are unchanged. The original descriptor pre-use compatibility item remains open; unrelated REA bugs remain recorded separately.

Exact-name guidance: managed signal and Android counterexample

Experiment #2416, source pin 3719ecd7b18f11eff181d4ef923ae95389d2c8cc. Capture and exact-name discovery guidance are optional; default trials stay ephemeral and production APIs/providers/defaults remain unchanged.

Repeated same-runtime managed trials show a preliminary favorable signal for exact-name guidance. The second comparison has two selected-factually acceptable answers: input 103,301 → 58,336 (~43.5%), uncached input 30,597 → 20,192 (~34.0%), wall time 60.336 → 50.685 seconds (~16.0%). The first unguided answer omits classification.container and is not counted as equivalent completed work. A guided answer's additional native counts are explicitly checked against source arrays and integer type; original failed receipts remain. All full selected resource gates still preserve unknown final cgroup counters as failures.

Actual second-domain verification uses real NewPipe 0.29.1 and JADX 0.7.1/Java. A fresh SDK three-operation oracle passes, and both model answers preserve all requested package/class/onCreate facts, source bytes and cleanup. Guided total input is lower (99,913 → 89,220), but uncached input increases (19,273 → 26,756) and wall time worsens (66.797 → 76.936 seconds). This counterexample prevents promoting the hint into default/general guidance. Peak sampled family memory stays about 1.35–1.41 GB; no guard abort occurs, final physical counters remain unknown.

Continue the remaining static-contract/pre-use audit and accurate resource accounting independently; the original descriptor compatibility item is still open. Curated actual scope and negative findings: github.com/morluto/rea@3719ecd7b1/experiments/analysis-efficiency/model-context.md

Context experiment and static-contract acceptance

Context experiment #2416 merged as ee87111009ace2ca4ef82c9aef09c82a37ca55f7.

#2427 merged as 4f4f6cd7b5d7a400b90772a138d7b9f942c2a556. The final static-contract checklist item is now checked with precise scope: five incompatible operation/CLI/factory/schema bindings are rejected by compiler-backed assignability assertions, and duplicate SDK registration occurs before provider invocation. Separate lazy owners and invalid-input-before-provider behavior are explicit. Production code/defaults remain unchanged. Arbitrary dynamic plugin ABI/version admission is still deferred, and unknown provider reply validation after execution is not relabeled pre-use admission.

The original three increments now have recorded scoped acceptance evidence. Continued performance work remains question/domain specific: actual managed discovery shows one favorable acceptable pair; real Android shows lower total input but worse uncached input/time. Both outcomes stay documented rather than generalizing a default recommendation.

Next measured-cost improvement: private feasibility probes retain an observer in an owned cgroup until the payload exits, then witness counters only when the observer is the sole remaining process. Actual success, exit-code-3 and a bounded 16 MiB Node allocation preserve exit codes and yield kernel peak/CPU/event observations. These are payload-completion witnesses, not final whole-scope counters; the existing terminal unknowns and safeguards are unchanged. No new resource measurement code is committed yet. Continue from latest main in a fresh isolated worktree and verify cleanup, missing witnesses, failure/cancellation and capacity before integrating it.

Resource measurement: optional payload-completion observer

Implemented in #2431, commit ca2d15b3ee965bd7ab27204cdf4b96b117d148c1.

The opt-in observer preserves default receipts, APIs, resource safeguards, and final whole-scope unknowns. Actual managed SDK pairs, WABT, JADX, and Codex runs verify only the explicitly recorded payload-completion phase. Mixed task timings and the unexplained initial outlier prevent a speed recommendation; raw JSON reduction is still not equated with model-token savings. Curated source-owned evidence: resource-counters.md. Raw receipts stay private outside Git.

The original three increments now have scoped acceptance evidence. Further changes should be tied to an observed recurring analyst question and verified against actual total/cached/uncached model usage and time to a factually acceptable answer, rather than expanding the plugin architecture without a demonstrated need.

Android package delivery: real results and migration

Implemented in #2438, commit f254f5ac2b804b353a711264bb178f43fdf07867.

The Android path now offers explicit package summary and exact retained manifest pages through the existing view workflow. Existing complete requests, CLI output, provider requests, Evidence identity and session lifetime remain unchanged. Actual old runtime requests and authentic old Evidence import/view/export pass the recorded compatibility checks; no automatic fallback to older servers is claimed.

Real NewPipe/JADX SDK pairs preserve all requested facts and settings: package reply 119,527 → 8,659 bytes (about 92.8% reduction), and combined three replies 149,577 → 38,709 bytes. SDK workflows take 23.694–24.509 seconds. These measurements establish delivery savings, without an engine/CPU/memory or general task-time recommendation.

Actual Codex outcomes are deliberately retained: three of four trials answer the original question correctly; summary1 spends more tokens/time after three rejected client inputs and repeated work, while summary2 uses the intended three successful calls but still establishes no token/time gain. The final complete control receives empty client tool metadata, makes zero MCP calls and fails the facts; its short time is not equivalent completed work. The visibility cause remains unknown and is recorded locally for investigation, without changing unrelated REA behavior. All profiles are removed and APK bytes remain unchanged.

One CPU, unchanged 3 GiB early-stop / 4 GiB hard memory / no swap / 192 tasks remain in force. Actual SDK/model/continuation phase witnesses verify payload cleanup with no limit events at that phase; final whole-scope counters remain unknown and the complete resource grader is not relabeled successful. Raw receipts stay private outside Git.

Curated evidence and reproduction: Android package delivery and model outcomes. Twenty-seven relevant SDK/domain/Android checks pass. Protocol fixtures are distinguished from real JADX verification.

The original three increments and all 21 recorded acceptance items now have scoped evidence, followed by the requested additional managed/native/Android migration and real application checks. General plugin SDK, dynamic ABI admission and persistent cross-session engine caches remain deferred by the plan. Unavailable hosts/providers and incomplete model answers remain explicitly unverified. This completes the current implementation/review/merge cycle; the issue can continue tracking optional gradual domain coverage without a claim that every historical client or advertised provider has been verified.

The audit is now implemented in PR #2455 (Flutter/Dart AOT retained summary + exact string-pool pages). Two real LocalSend SDK pairs preserve the selected facts while reducing the AOT reply from 151,341 to 12,037 compact JSON bytes (92.05%). Whole SDK workflows remain approximately 5.1 seconds; this is not a speed or model-token claim. A fresh previous-runtime complete request matches, and 15 public MCP migration calls reconstruct all 2,716 original strings with the APK absent and preserve the original exported Evidence byte values. Actual Codex comparisons are still running; all errors/retries remain counted.

The new inspect_web_network_capture SAZ implementation already advertises opt-in summary and retained capture pages, original archive-member coordinates and encoded bytes. It decodes all records before ordinal selection and rejects malformed/oversized input without partial success. Therefore, first measure genuine public SAZ captures using the existing summary/page workflow; do not add another delivery API or silently reduce decoding/credential-redaction semantics. Real SAZ performance is unverified in this Flutter trial.

The frozen Flutter runtime remains source revision 811034a7283c9751a3ecbff33e8b2f28bec55793, compiled file-table SHA-256 dabbb63536c5862be839ecdc0f3eaad05b29c2a3816f57041528d30f754311be. Ongoing comparison cohorts will finish against that same pin.

Two complete/summary real Codex pairs are now finished on the frozen Flutter runtime. All four answers pass the selected factual checks, preserving snapshot fields/nulls, target identity, counts, lower bounds, partial coverage, original limitations and observed response Evidence IDs. Profiles are removed and artifact bytes unchanged.

Pair	Total input reduction	Uncached input reduction	Reported output reduction	Whole-task time reduction
1	48.75%	33.63%	47.59%	23.95%
2	42.38%	42.52%	31.66%	30.30%

Complete trials make 3 / 2 attempts; the first includes a wrong parameter followed by correction and a repeated successful call. Summary trials make one successful call each. These actual task decisions remain counted and limit causal claims: benefits include explicit returned counts and fewer repeated calls, rather than proving serialization alone or engine acceleration. Raw discovery/errors/retries remain retained. Earlier SDK pairs show 92.05% fewer reply bytes and approximately unchanged 5.1-second SDK workflows. Payload observations are verified separately; final whole-scope counters remain unknown and the strict resource grade stays false.

Curated metrics, limitations and reproduction: Flutter AOT summary. SQLite and packet/signal/SAZ captures remain subsequent measurement lanes at this historical checkpoint.

Small-PCAP experiment: completed decision

Recorded in #2640, merged at c7105d9723c835b5e0122f5fc6cfbea86265c349. Curated corpus, measurements and reproduction.

For two official Wireshark HTTP captures and a fixed metadata/URI question, summary/page returns more than twice the SDK JSON and about 51% more total model input in both real-model pairs. Uncached input and elapsed time are mixed. Keep existing complete defaults; no new production optimization is justified for this corpus/question.

Evidence: eight actual SDK workflows, four actual Codex CLI tasks, independent raw-frame and public CLI/MCP checks, and 18 authenticated original Evidence records. All four stored answers pass separate factual and exact-workflow regrading; 34 context/grading regressions and six discovered comparator scenarios pass. Original measured runtime remains 3ae826ceba6f25b08bce50bcb51001209bc16b57; measurements are unchanged and models were not rerun for review fixes.

Final scope is nine experiment files and one evaluation test, with production APIs/defaults/cache unchanged. Raw captures/results/transcripts/configuration remain private. Serial one-CPU/3-GiB-early-stop/4-GiB-hard/no-swap controls remain in force; unavailable terminal whole-scope counters stay unknown. Future larger-capture, non-HTTP and discovery-guided field-selection results remain unmeasured.
